What is OBFUSCATION? What does OBFUSCATION mean? OBFUSCATION meaning - OBFUSCATION pronunciation - OBFUSCATION definition - OBFUSCATION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Obfuscation is the obscuring of intended meaning in communication, making the message confusing, willfully ambiguous, or harder to understand. It may be intentional or unintentional (although the former is usually connoted) and may result from circumlocution (yielding wordiness) or from use of jargon or even argot (yielding economy of words but excluding outsiders from the communicative value). Unintended obfuscation in expository writing is usually a natural trait of early drafts in the writing process, when the composition is not yet advanced, and it can be improved with critical thinking and revising, either by the writer or by another person with sufficient reading comprehension and editing skills. The name comes from Latin obfuscatio, from obfuscare ("to darken"). Obfustication is a common variant of the name, especially in British English. Synonyms include beclouding and abstrusity. Obscurantism is intentional obscurity, whether by withholding communication, obfuscating it, or both. Obfuscation may be used for many purposes. Doctors have been accused of using jargon to conceal unpleasant facts from a patient; American author Michael Crichton claimed that medical writing is a "highly skilled, calculated attempt to confuse the reader". B. F. Skinner, noted psychologist, commented on medical notation as a form of multiple audience control, which allows the doctor to communicate to the pharmacist things which might be opposed by the patient if they could understand it. "Eschew obfuscation", also stated as "eschew obfuscation, espouse elucidation", is a humorous fumblerule used by English teachers and professors when lecturing about proper writing techniques. Literally, the phrase means "avoid being unclear" or "avoid being unclear, support being clear", but the use of relatively uncommon words causes confusion in much of the audience (those lacking the vocabulary), making the statement an example of irony, and more precisely a heterological phrase. The phrase has appeared in print at least as early as 1959, when it was used as a section heading in a NASA document. An earlier similar phrase appears in Mark Twain's Fenimore Cooper's Literary Offenses, where he lists rule fourteen of good writing as "eschew surplusage". The philosopher Paul Grice used the phrase in the "Maxim of Manner", one of the Gricean maxims. In white-box cryptography, obfuscation refers to the protection of cryptographic keys from extraction when they are under the control of the adversary, e.g., as part of a DRM scheme.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, the eXtended Sparse Linearization (XSL) attack is a method of cryptanalysis for block ciphers. The attack was first published in 2002 by researchers Nicolas Courtois and Josef Pieprzyk. It has caused some controversy as it was claimed to have the potential to break the Advanced Encryption Standard (AES) cipher, also known as Rijndael, faster than an exhaustive search. Since AES is already widely used in commerce and government for the transmission of secret information, finding a technique that can shorten the amount of time it takes to retrieve the secret message without having the key could have wide implications. The method has a high work-factor, which unless lessened, means the technique does not reduce the effort to break AES in comparison to an exhaustive search. Therefore, it does not affect the real-world security of block ciphers in the near future. Nonetheless, the attack has caused some experts to express greater unease at the algebraic simplicity of the current AES. In overview, the XSL attack relies on first analyzing the internals of a cipher and deriving a system of quadratic simultaneous equations. These systems of equations are typically very large, for example 8,000 equations with 1,600 variables for the 128-bit AES. Several methods for solving such systems are known. In the XSL attack, a specialized algorithm, termed eXtended Sparse Linearization, is then applied to solve these equations and recover the key. The attack is notable for requiring only a handful of known plaintexts to perform; previous methods of cryptanalysis, such as linear and differential cryptanalysis, often require unrealistically large numbers of known or chosen plaintexts. Solving multivariate quadratic equations (MQ) over a finite set of numbers is an NP-hard problem (in the general case) with several applications in cryptography. The XSL attack requires an efficient algorithm for tackling MQ. In 1999, Kipnis and Shamir showed that a particular public key algorithm, known as the Hidden Field Equations scheme (HFE), could be reduced to an overdetermined system of quadratic equations (more equations than unknowns). One technique for solving such systems is linearization, which involves replacing each quadratic term with an independent variable and solving the resultant linear system using an algorithm such as Gaussian elimination. To succeed, linearization requires enough linearly independent equations (approximately as many as the number of terms). However, for the cryptanalysis of HFE there were too few equations, so Kipnis and Shamir proposed re-linearization, a technique where extra non-linear equations are added after linearization, and the resultant system is solved by a second application of linearization. Re-linearization proved general enough to be applicable to other schemes. In 2000, Courtois et al. proposed an improved algorithm for MQ known as XL (for eXtended Linearization), which increases the number of equations by multiplying them with all monomials of a certain degree. Complexity estimates showed that the XL attack would not work against the equations derived from block ciphers such as AES. However, the systems of equations produced had a special structure, and the XSL algorithm was developed as a refinement of XL which could take advantage of this structure. In XSL, the equations are multiplied only by carefully selected monomials, and several variants have been proposed. Research into the efficiency of XL and its derivative algorithms remains ongoing (Yang and Chen, 2004). Courtois and Pieprzyk (2002) observed that AES (Rijndael) and partially also Serpent could be expressed as a system of quadratic equations. The variables represent not just the plaintext, ciphertext and key bits, but also various intermediate values within the algorithm. The S-box of AES appears to be especially vulnerable to this type of analysis, as it is based on the algebraically simple inverse function. ...

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Differential fault analysis (DFA) is a type of side channel attack in the field of cryptography, specifically cryptanalysis. The principle is to induce faults—unexpected environmental conditions—into cryptographic implementations, to reveal their internal states. For example, a smartcard containing an embedded processor might be subjected to high temperature, unsupported supply voltage or current, excessively high overclocking, strong electric or magnetic fields, or even ionizing radiation to influence the operation of the processor. The processor may begin to output incorrect results due to physical data corruption, which may help a cryptanalyst deduce the instructions that the processor is running, or what its internal data state is. For DES and Triple DES, about 200 single-flipped bits are necessary to obtain a secret key. DFA was also applied successfully to the AES cipher. Many countermeasures have been proposed to defend from this kind of attacks. Most of them are based on error detection schemes.

What is SIDE-CHANNEL ATTACK? What does SIDE-CHANNEL ATTACK mean? SIDE-CHANNEL ATTACK meaning - SIDE-CHANNEL ATTACK definition - SIDE-CHANNEL ATTACK explanation.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a side-channel attack is any attack based on information gained from the physical implementation of a cryptosystem, rather than brute force or theoretical weaknesses in the algorithms (compare cryptanalysis). For example, timing information, power consumption, electromagnetic leaks or even sound can provide an extra source of information, which can be exploited to break the system. Some side-channel attacks require technical knowledge of the internal operation of the system on which the cryptography is implemented, although others such as differential power analysis are effective as black-box attacks. Many powerful side-channel attacks are based on statistical methods pioneered by Paul Kocher. Attempts to break a cryptosystem by deceiving or coercing people with legitimate access are not typically called side-channel attacks: see social engineering and rubber-hose cryptanalysis. For attacks on computer systems themselves (which are often used to perform cryptography and thus contain cryptographic keys or plaintexts), see computer security. The rise of Web 2.0 applications and software-as-a-service has also significantly raised the possibility of side-channel attacks on the web, even when transmissions between a web browser and server are encrypted (e.g., through HTTPS or WiFi encryption), according to researchers from Microsoft Research and Indiana University. General classes of side channel attack include: Cache attack — attacks based on attacker's ability to monitor cache accesses made by the victim in a shared physical system as in virtualized environment or a type of cloud service. Timing attack — attacks based on measuring how much time various computations take to perform. Power-monitoring attack — attacks that make use of varying power consumption by the hardware during computation. Electromagnetic attack — attacks based on leaked electromagnetic radiation, which can directly provide plaintexts and other information. Such measurements can be used to infer cryptographic keys using techniques equivalent to those in power analysis or can be used in non-cryptographic attacks, e.g. TEMPEST (aka van Eck phreaking or radiation monitoring) attacks. Acoustic cryptanalysis — attacks that exploit sound produced during a computation (rather like power analysis). Differential fault analysis — in which secrets are discovered by introducing faults in a computation. Data remanence — in which sensitive data are read after supposedly having been deleted. Row hammer — in which off-limits memory can be changed by accessing adjacent memory. Optical - in which secrets and sensitive data can be read by visual recording using a high resolution camera, or other devices that have such capabilities (see examples below). In all cases, the underlying principle is that physical effects caused by the operation of a cryptosystem (on the side) can provide useful extra information about secrets in the system, for example, the cryptographic key, partial state information, full or partial plaintexts and so forth. The term cryptophthora (secret degradation) is sometimes used to express the degradation of secret key material resulting from side-channel leakage. A cache side-channel attack works by monitoring security critical operations such as AES T-table entry or modular exponentiation multiplicand accesses. Attacker then is able to recover the secret key depending on the accesses made (or not made) by the victim, deducing the encryption key. Also, unlike some of the other side-channel attacks, this method does not create a fault in the ongoing cryptographic operation and is invisible to the victim.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ A tripwire is a passive triggering mechanism. Typically, a wire or cord is attached to some device for detecting or reacting to physical movement. A tripwire may be a wire attached to one or more mines — normally bounding mines and the fragmentation type — in order to increase their activation area.. Alternatively, tripwires are frequently used in boobytraps, whereby a tug on the wire (or release of tension on it) will detonate the explosives. Soldiers sometimes detect the presence of tripwires by spraying the area with Silly String. It will settle to the ground in areas where there are no wires; if there are any, the string will be suspended in the air but not set them off due to its light weight. It was used by U.S. troops in Iraq for this purpose. A newer method is the use of green line lasers to illuminate and detect trip and command wires. The bright laser line reflects off of the tripwire and can be seen by the bomb tech.

What is SECURE CHANNEL? What does SECURE CHANNEL mean? SECURE CHANNEL meaning - SECURE CHANNEL definition - SECURE CHANNEL explanation.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a secure channel is a way of transferring data that is resistant to overhearing and tampering. A confidential channel is a way of transferring data that is resistant to overhearing (i.e., reading the content), but not necessarily resistant to tampering. An authentic channel is a way of transferring data that is resistant to tampering but not necessarily resistant to overhearing. There are no perfectly secure channels in the real world. There are, at best, only ways to make insecure channels (e.g., couriers, homing pigeons, diplomatic bags, etc.) less insecure: padlocks (between courier wrists and a briefcase), loyalty tests, security investigations, and guns for courier personnel, diplomatic immunity for diplomatic bags, and so forth. In 1976, two researchers proposed a key exchange technique (now named after them)—Diffie–Hellman key exchange (D-H). This protocol allows two parties to generate a key only known to them, under the assumption that a certain mathematical problem (e.g., the Diffie–Hellman problem in their proposal) is computationally infeasible (i.e., very very hard) to solve, and that the two parties have access to an authentic channel. In short, that an eavesdropper—conventionally termed 'Eve', who can listen to all messages exchanged by the two parties, but who can not modify the messages—will not learn the exchanged key. Such a key exchange was impossible with any previously known cryptographic schemes based on symmetric ciphers, because with these schemes it is necessary that the two parties exchange a secret key at some prior time, hence they require a confidential channel at that time which is just what we are attempting to build. It is important to note that most cryptographic techniques are trivially breakable if keys are not exchanged securely or, if they actually were so exchanged, if those keys become known in some other way— burglary or extortion, for instance. An actually secure channel will not be required if an insecure channel can be used to securely exchange keys, and if burglary, bribery, or threat aren't used. The eternal problem has been and of course remains—even with modern key exchange protocols—how to know when an insecure channel worked securely (or alternatively, and perhaps more importantly, when it did not), and whether anyone has actually been bribed or threatened or simply lost a notebook (or a notebook computer) with key information in it. These are hard problems in the real world and no solutions are known—only expedients, jury rigs, and workarounds. Researchers have proposed and demonstrated quantum cryptography in order to create a secure channel. If the current understanding of this subject of quantum physics is adequate, quantum cryptography facilitates the exchange of theoretically uneavesdroppable, non-interceptable, non-tamperable data. The mechanism is related to the uncertainty relation. It is not clear whether the special conditions under which it can be made to work are practical in the real world of noise, dirt, and imperfection in which most everything is required to function. Thus far, actual implementation of the technique is exquisitely finicky and expensive, limiting it to very special purpose applications. It may also be vulnerable to attacks specific to particular implementations and imperfections in the optical components of which the quantum cryptographic equipment is built. While implementations of classical cryptographic algorithms have received worldwide scrutiny over the years, only a limited amount of public research has been done to assess security of the present-day implementations of quantum cryptosystems, mostly because they are not in widespread use as of 2014. Security definitions for a secure channel try to model its properties independently from its concrete instantiation. A good understanding of these properties is needed before designing a secure channel, and before being able to assess its appropriateness of employment in a cryptographic protocol. This is a topic of provable security. A definition of a secure channel that remains secure, even when used in arbitrary cryptographic protocols is an important building block for universally composable cryptography....

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Anti-tamper software (or tamper-resistant software) is software which makes it harder for an attacker to modify it. The measures involved can be passive such as obfuscation to make reverse engineering difficult or active tamper-detection techniques which aim to make a program malfunction or not operate at all if modified. It is essentially tamper resistance implemented in the software domain. It shares certain aspects but also differs from related technologies like copy protection and trusted hardware, though it is often used in combination with them. Anti-tampering technology typically makes the software somewhat larger and also has a performance impact. There are no provably secure software anti-tampering methods, thus the field is an arms race between attackers and software anti-tampering technologies. Tampering is generally malicious, to gain control over some aspect of the software with an unauthorized modification that alters the computer program code and behaviour. Examples include installing rootkits and backdoors, disabling security monitoring, subverting authentication, malicious code injection for the purposes of data theft or to achieve higher user privileges, altering control flow and communication, license code bypassing for the purpose of software piracy, code interference to extract data or algorithms and counterfeiting. Software applications are vulnerable to the effects of tampering and code changes throughout their lifecycle from development and deployment to operation and maintenance. Anti-tamper protection can be applied as either internally or externally to the application being protected. External anti-tampering is normally accomplished by monitoring the software to detect tampering. This type of defense is commonly expressed as malware scanners and anti-virus applications. Internal anti-tampering is used to turn an application into its own security system and is generally done with specific code within the software that will detect tampering as it happens. This type of tamper proofing defense may take the form of runtime integrity checks such as cyclic redundancy checksums, anti-debugging measures, encryption or obfuscation. Execution inside a virtual machine has become a common anti-tamper method used in recent years for commercial software; it is used for example in StarForce and SecuROM. Some anti-tamper software uses white-box cryptography, so cryptographic keys are not revealed even when cryptographic computations are being observed in complete detail in a debugger. A more recent research trend is tamper-tolerant software, which aims to correct the effects of tampering and allow the program to continue as if unmodified. A simple (and easily defeated) scheme of this kind was used in the Diablo II video game, which stored its critical player data in two copies at different memory locations and if one was modified externally, the game used the lower value. Anti-tamper software is used in many types of software products including: embedded systems, financial applications, software for mobile devices, network-appliance systems, anti-cheating in games, military, license management software, and digital rights management (DRM) systems. Some general-purpose packages have been developed which can wrap existing code with minimal programing effort; for example the SecuROM and similar kits used in the gaming industry, though they have the downside that semi-generic attacking tools also exist to counter them. Malicious software itself can and has been observed using anti-tampering techniques, for example the Mariposa botnet.

The Cardboard Box Reform - Nixon's Ghost Bill & A Crucial Flaw in Democracy
 
01:02:38
James D'Angelo (Winner 2014 MIT Climate CoLab, ex-NASA scientist) uncovers a crucial flaw in American democracy. Incredibly, the solution – which lays at the heart of all current social concerns (inequality, the recession, political division, government disapproval, Citizens United, civil rights and corruption) – costs under 5 dollars. James presents a breathtaking new look at congressional transparency and the troubles it has wrought by opening the doors to special interests and the wealthy. So, welcome to the world of Martin Gilens' 2014 paper and flatline graph. Also welcome to the world created by electronic voting machines and the Legislative Reorganization Act of 1970 (passed on October 26, 1970). Unheard of in any current political discussion, this act of Congress has produced endless avenues for lucrative lobbying of special interest groups. UPDATE (2017) Since posting this video James has partnered with Harvard Professor of Congress David King and author Brent Ranalli to further investigate this problem of transparency. The results are even more striking and powerful than initially proposed in this video. You can follow their latest work, read their papers and see their latest talks here http://congressionalresearch.org/ Follow James on Twitter @JamesGDAngelo REFERENCES For much more on this topic see our website https://www.congressionalresearch.org Here are citations from over a hundred scholars who find similar problems with transparency http://congressionalresearch.org/Citations.html Here is a good first page for information on transparency http://congressionalresearch.org/SevenDeadlyMyths.html D'Angelo has found the most unusual (indeed counterintuitive) source for our current explosion in inequality and campaign financing in a place that most economists would't consider, the secret ballot. Considered by many to have crushed the first gilded age, the secret ballot was introduced en masse in the US starting in 1890. By 1940 it was everywhere (all citizens voted privately and most bills in congress were decided by teller or voice vote). And then for 30 years life was pretty good. Inequality was dropping, so were a number of other metrics, partisanship, campaign finance, national debt etc. And then, October 26th, 1970 there was a crack in our air-tight democracy - The Legislative Reorganization Act of 1970 opened up the votes of Congress (the committee of the whole). Dubbed a ’sunshine law’, this bill has only ever been considered a good thing. The trouble is, we vote in secret for a reason. Reasons most Americans forget. Every time votes are public we get massive explosion in two types of electoral fraud. They first form of Electoral Fraud is Vote Buying (Tammany Hall, etc), with as much as 20% of the electorate being paid to vote a specific way (often poor individuals being paid with a chicken wing or a beer). The second form is Voter Intimidation, often times people would vote in the local court house, and they would just announce their vote to the local staff. The trouble with voting publicly (stating your votes to a clerk) is that often citizens were voting on deputies and sheriffs who were sitting right there in the court house, listening. It is hard to vote against an evil Sheriff if he can see how you vote. It is easy to see the problem there. Interestingly, this is exactly what now happens in our Congress. Inside of congress, Voter intimidation leads to massive partisanship and polarization, and the vote buying leads to what some congressmen call ‘legalized bribery’. The convictions, admissions and stories of this are common (Jack Abramoff, ABACAM, etc etc). And this change in 1970 has led to a feedback loop that responds to the ever increasing money in Washington. Indeed The Legislative Reorganization Act of 1970 is the cause for the phenomenal growth of K-street. And all the big firms were born just months after it passed. The trouble is no one has ever called it what it is, Electoral Fraud. And the beauty is, all these alarming trends can be reversed by re-instating the secret ballot. Examples of Electoral Fraud in Congress: 1. Intimidation - John Boehner telling congressmen how to vote. Leads to massive partisanship. 2. Vote Buying - Abscam, Jack Abramoff and others, plus all the revolving door events 3. Logrolling - Congressmen trade votes (Tip O'Neill built Tufts into a major PRIVATE university by logrolling)

Invented by Ray Tomlinson, email first entered limited use in the 1960s and by the mid-1970s had taken the form now recognized as email. Email operates across computer networks, which today is primarily the Internet. Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging. Today's email systems are based on a store-and-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need to connect only briefly, typically to a mail server or a webmail interface, for as long as it takes to send or receive messages. Originally an ASCII text-only communications medium, Internet email was extended by Multipurpose Internet Mail Extensions (MIME) to carry text in other character sets and multimedia content attachments. International email, with internationalized email addresses using UTF-8, has been standardized, but as of 2017 it has not been widely adopted.The history of modern Internet email services reaches back to the early ARPANET, with standards for encoding email messages published as early as 1973 (RFC 561). An email message sent in the early 1970s looks very similar to a basic email sent today. Email had an important role in creating the Internet, and the conversion from ARPANET to the Internet in the early 1980s produced the core of the current services.

DEF CON 23 - Ryan Castellucci - Cracking CryptoCurrency Brainwallets
 
42:49
Imagine a bank that, by design, made everyone's password hashes and balances public. No two-factor authentication, no backsies on transfers. Welcome to "brainwallets", a way for truly paranoid cryptocurrency users to wager their fortunes on their ability to choose a good password or passphrase. Over the last decade, we've seen the same story play out dozens of times - a website is broken into, the user database is posted online, and most of the password hashes are cracked. Computers are now able make millions, billions or even trillions of guesses per second. Every eight character password you can type on a standard keyboard and every combination of five common english words could be tried in less than a day by today's botnets. Can people come up with passphrases able to stand up to that when money is on the line? Let's find out. For this talk, I will be releasing my high speed brainwallet cracker, "Brainflayer". I'll cover a history of brainwallets, safer passphrase-based wallet generation, passphrase security, in-the-wild cracking activity, and how I accidently stole 250 Bitcoins (and tracked down the owner to give them back). Ryan Castellucci has been interested in cryptography since childhood when his parents gave him a copy of "Codes, Ciphers and Secret Writing". He soon learned to program and wrote a tool to crack simple substitution ciphers. More recently, he co-spoke with Dan Kaminsky at DEF CON 22 and was a finalist in the 2014 Underhanded Crypto Contest. For his day job at White Ops, he finds new and exciting ways to tease out the subtle differences between bots and human-controlled web browsers.

All generations of the iPhone use Apple's iOS mobile operating system software. The first-generation iPhone was released on June 29, 2007, and multiple new hardware iterations with new iOS releases have been released since. The user interface is built around the device's multi-touch screen, including a virtual keyboard. The iPhone has Wi-Fi and can connect to cellular networks. An iPhone can shoot video (though this was not a standard feature until the iPhone 3GS), take photos, play music, send and receive email, browse the web, send and receive text messages, follow GPS navigation, record notes, perform mathematical calculations, and receive visual voicemail. Other functionality, such as video games, reference works, and social networking, can be enabled by downloading mobile apps. As of January 2017, Apple's App Store contained more than 2.2 million applications available for the iPhone. Apple has released eleven generations of iPhone models, each accompanied by one of the eleven major releases of the iOS operating system. The original first-generation iPhone was a GSM phone and established design precedents, such as a button placement that has persisted throughout all releases and a screen size maintained for the next four iterations. The iPhone 3G added 3G network support, and was followed by the 3GS with improved hardware, the 4 with a metal chassis, higher display resolution and front-facing camera, and the 4S with improved hardware and the voice assistant Siri. The iPhone 5 featured a taller, 4-inch display and Apple's newly introduced Lightning connector. In 2013, Apple released the 5S with improved hardware and a fingerprint reader, and the lower-cost 5C, a version of the 5 with colored plastic casings instead of metal. They were followed by the larger iPhone 6, with models featuring 4.7-and-5.5-inch (120 and 140 mm) displays. The iPhone 6S was introduced the following year, which featured hardware upgrades and support for pressure-sensitive touch inputs, as well as the SE—which featured hardware from the 6S but the smaller form factor of the 5S. In 2016, Apple unveiled the iPhone 7 and 7 Plus, which add water resistance, improved system and graphics performance, a new rear dual-camera setup on the Plus model ...

What does COMMON INTERFACE mean? COMMON INTERFACE meaning - COMMON INTERFACE definition - COMMON INTERFACE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. In Digital Video Broadcasting, the Common Interface is a technology which allows separation of conditional access functionality from a digital TV receiver-decoder (Host) into a removable conditional-access module (CAM). It is also referenced as DVB-CI for Digital Video Broadcast - Common Interface. The host is responsible for tuning to pay TV channels and demodulation of the RF signal, while CAM is responsible for CA descrambling. The Common Interface allows them to communicate with each other. The Common Interface can be used for pay-to-view TV ; a module is used to interface between the pay-to-view card and the TV or device. This allows manufacturers to install a single (common) interface into their devices rather than many. It is a similar concept to USB. All Common Interface equipment must comply with the EN 50221-1997 standard. This is a defined standard that enables the addition of a conditional-access module (CAM) in a DTV receiver to adapt it to different kinds of cryptography. Indeed, one of Digital Video Broadcasting's main strengths is the option of implementing the required conditional access capability on the Common Interface. This allows broadcasters to use modules containing solutions from different suppliers in the same broadcast system, thus increasing their choice of anti-piracy options. The interconnect is formed between a host and a module. Examples of a host are a digital television or digital set-top box. The EN 50221 specification allows many types of module but only the conditional-access module (CAM) has found popularity because of the pay TV market. A DVB receiver may have one or two slots implementing the Common Interface (CI). The CI uses the conditional-access module (PCMCIA) connector and conforms to the Common Scrambling Algorithm (CSA), the normative that specifies that such a receiver must be able to accept DES (Data Encryption Standard) keys in intervals of some milliseconds, and use them to decode private channels according to a specific algorithm. Those algorithms are proprietary to individual suppliers. Each one uses their own algorithms and there is no defined standard for them. As the full MPEG-2 transport data stream comes out of the demodulator, and error correction units, the DTV Receiver sends it through the card plugged into the Common Interface, before it is processed by the MPEG demultiplexer in the receiver. If several CI cards are present, the MPEG transport data stream will be passed sequentially through all these cards. An embedded CAM may not physically exist, as it may be in CPU software. In such a case, only the smart card reader normally in the CAM is fitted and not the PCMCIA type CI slots. Even if the Common Interface has been created to resolve cryptography issues, it can have other functions using other types of modules such as Web Browser, iDTV (Interactive Television), and so forth. In Europe, DVB-CI is obligatory in all iDTV terminals.

Introducing Sno-Caps - The People's Cap-And-Trade (2014 MIT Award Winner)
 
40:34
Sno-caps is a brand new idea (and current winner of the 2014 MIT Climate CoLab Contest - see link below) presented here for the first time. It is a system that combines Regulation by Reputation (i.e. ebay, uber, yelp) with Bitcoin's public ledger (accounting and smart contracts) to fight global climate change. Here is the elevator pitch: Using public ledgers we can launch a global cap-and-trade today that sidesteps government and gives equal shares to everyone on earth. While the idea is relatively simple (especially compared to all other cap-and-trade systems), it only makes sense with the proper context. That is the goal of this video, to present the viewer with all the necessary understanding (Tragedy of the Commons, failing of current Cap-And-Trade schemes) to understand the scope of this idea. We hope you'll agree that there is a better way. Here is the link to our MIT Climate CoLab proposal. http://climatecolab.org/plans/-/plans/contestId/1300404/planId/1305801 Please consider commenting on this forum and showing your support here. Even though we are a late entry, we are currently number two in the rankings. When the MIT contest ends (link above) we will launch our site at www.snocaps.org Below is the link to our white paper http://www.worldbitcoinnetwork.com/snocaps.pdf While comments etc on the MIT contest are the best, donations are also much appreciated: https://blockchain.info/address/1javsf8GNsudLaDue3dXkKzjtGM8NagQe WBN's Bitcoin 101 Blackboard Series is a full beginner to expert course in Bitcoin, brought to you by host, James D'Angelo.

LIKE | COMMENT | SHARE | SUBSCRI अल्बम -महाराची तलवार संगीत गायक -बाळू शिंदे गीत _सुनिल सकट निर्माता -शशिकांत अस्वरे भिमा कोरेगांव की लड़ाई १ जनवरी १८१८ इसवी में पुणा (पुणे) स्थित कोरेगाव गांव में भिमा नदी के पास उत्तरी पू्र्वी में हुई थी। पेशवा बाजीराव के मराठा साम्राज्य में अस्पृश्यता चरमसिमा पर पोहोचकर उसका कठोर पालन किया जा रहा था, इसलिए महार लोग उनके विरोध में युद्ध में खडे हुए थे। यह लड़ाई महार और पेशवा सैनिकों के बिच लड़ी गई थी। अंग्रेजों की तरफ ५०० लड़ाके, जिनमें ४५० महार सैनिक थे और पेशवा बाजीराव द्वितीय के २८,००० पेशवे सैनिक थे, मात्र ५०० महार सैनिकों ने पेशवा की शक्तिशाली २८ हजार मराठा फौज को हरा दिया था। महार सैनिकों को उनकी वीरता और साहस के लिए सम्मानित किया गया और उनके सन्मान में भीमा कोरेगांव में स्मारक भी बनवाया जिनपर महारों के नाम लिखे गए। ब्रिटिश रेजिडेंट की अधिकारिक रिपोर्ट के अनुसार इसे नायकत्व वाला कर्त्य कहा गया और सैनिकों के अनुशासित और समर्पित साहस और स्थिरता की तारीफ की गई। यह युद्ध बहुत ही महत्त्व का था। प्रथम अंग्रेजो की छोटी सी टुकड़ी ने पेशवा को हरा दिया जिसने पेशवा साम्राज्य का सफाया करने में मदद की। दूसरा अछूत महारो को अपनी वीरता दिखा जाती बंधन को तोड़ने का मौका। The Battle of Koregaon took place on January 1, 1818, at the bank of the river Bhima in Koregaon, northwest of Pune, India. A small force of 500 men of the 2nd Battalion 1st Regiment of the Bombay Native Light Infantry (mostly Mahars) under the command of Capt. F. F. Staunton fought continuously without rest or respite, food or water for twelve hours against a large force of 20,000 horse and 8,000 infantry of Maratha Leader Peshwa Baji Rao II who was threatening the British garrisons at Kirkee and Poona. In November 1817, Peshwas devastated the Regency of Pune giving no scope for the British army to retaliate successfully. The British commanding officer in Pune called the Chief of the second Battalion-first Regiment Native Infantry for help which was encamped in the Shirur Taluka of Pune district. This contingent, with only 500 foot soldiers and 250 cavalry both predominantly having with Mahars defeated the mighty Peshwa army of 8,000 foot soldiers and 20,000 cavalry. The Peshwa's troops inexplicably withdrew that evening, despite their overwhelming numbers, giving the British an important victory. The men of the 2/1st Regiment Bombay Native Infantry, who fought in this battle, were honored for their bravery. The official report to the British Residents at Poona recalls the "heroic valour and enduring fortitude" of the soldiers, the "disciplined intrepidity" and "devoted courage and admirable consistency" of their actions.
