Cryptography basics: What is Encryption and Decryption
Get Full Course: http://www.engineeringmentor.com/CNYTv3 Networks #3: This tutorial introduces the Cryptography basics. It also explains what is Encryption and Decryption. a) Cryptography basics (00:21):http://youtu.be/BEb_AnPWPwY?t=21s how do we provide this security during transmission? Well, One way of ensuring security can be use of CRYPTOGRAPHY! Cryptography is a field of network security which deals with hiding "real" infromation when it is under transmission between the two parties. Usually, the real information is transformed or hidden into another message and transmitted over the network. This transformed message in itself will make no sense even if any hacker gets hold of this information. When it reaches the destination, the receipent will know a method to de-transform the garbage message into the original information which the sender had sent.method of transforming message at sender's side and de transforming at reciever's side forms the basic model of Cryptography. b) Encryption and Decryption (3:57):http://youtu.be/BEb_AnPWPwY?t=3m57s First, the information to be transmitted, called as plain text(or message) is fed to an Encryption system. The Encyrption system uses a key to convert the plain text to encyrpted form which looks like garbage value. This is also called as cipher text. A corresponding key is used at the other end to decrypt the cipher text back to original message. When we say a key, it actually means a piece of string value which is fed to encyprtion and decryption algorithms along with the text for transformation. When the message reaches the destination, this system at the other end decrypts the cipher text into original message with the help of the key. This is called as Decryption System. The output of the Decryption System is the intended message. Depending on how the keys are shared, we can classify crytography as symmetric and asymmetric. If the keys used by both parties are same, then it is called symmetric key cryptography, or private key cryptography. If both parties use different keys for encyrption and decryption, then it is called asymmetric key cryptography or public key cryptography. video URL : https://www.youtube.com/watch?v=BEb_AnPWPwY Watch ALL CN VIDEOS: https://www.youtube.com/playlist?list=PL9OIoIp8YySF4mkIihOb_j2HZIRIlYuEx For more, visit http://www.EngineeringMentor.com Facebook: https://www.facebook.com/EngineeringMentor Twitter : https://twitter.com/Engi_Mentor

What is digital signature?
A digital signature is equivalent to a handwritten signature in paper, and a digital signature serves three basic purposes. Digital signature is commonly used for software distribution, financial transactions and other cases where it is important to detect forgery. Digital signatures are very popular with e-mail users. In this video, I will talk about the digital, uses, and the whole process of creating and sending digitally signed document over the Internet. Keep in mind, digital signature is not about encrypting document, just like paper-based signature.

Symmetric Key and Public Key Encryption
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Digital Signature in Hindi
This Tutorial Explain What is Digital Signature in Hindi. A Digital Signature in Hindi (not to be confused with a digital certificate) is a mathematical technique used to validate the authenticity and integrity of a message, software or digital document. It Covers Points like digital signature in cryptography in hindi, digital signature in network security and digital signature in dbms(advance database management system) Digital Signature Use Asymatric Key to Encrypt Data. Digital signatures are often used to implement electronic signatures, a broader term that refers to any electronic data that carries the intent of a signature How digital signatures work Digital signatures are based on public key cryptography, also known as asymmetric cryptography. Using a public key algorithm such as RSA, one can generate two keys that are mathematically linked: one private and one public. To create a digital signature, signing software (such as an email program) creates a one-way hash of the electronic data to be signed. The private key is then used to encrypt the hash. The encrypted hash -- along with other information, such as the hashing algorithm -- is the digital signature. The reason for encrypting the hash instead of the entire message or document is that a hash function can convert an arbitrary input into a fixed length value, which is usually much shorter. This saves time since hashing is much faster than signing. Subscribe my Channel: https://goo.gl/FYkHc5 Reference Link: https://en.wikipedia.org/wiki/Digital_signature

The Birthday Problem / Paradox
How many people do you need in a group together before you've got a 50% chance of two people sharing the same birthday? If you've never seen this before, the answer is likely to surprise you. The Birthday Problem is sometimes called the Birthday Paradox, but it's not a paradox in the true sense of the word, but it is an extremely counterintuitive result. In the 2nd half of the video I will demonstrate that the result is correct by using simple probability. Once you've watched this video, next time you're in a group of people of about the right size, why not try and find out if there are any shared birthdays!

MD5 Hash Tutorial - What the MD5 hash means and how to use it to verify file integrity.
Please like / share / subscribe if you like my MD5 hash tutorial! Here I explain how you use the MD5 hash of a file to verify its integrity in a simple MD5 hash tutorial. We use a windows based utility, md5sum.exe (http://www.etree.org/md5com.html) to check the integrity of a picture before and after we make an almost imperceptible change. Of course, we need not have used a picture, we could use any digital file to demonstrate the power of the MD5 hash for file integrity checking. As you will see in the video, using MD5 hashing, you can guarantee / verify the integrity of a Word document, a picture, a sound or video file or a software application. Reasons an integrity check might fail could be through file corruption on disk, communications corruption while downloading or even unauthorised tampering. I hope you enjoy the video, more coming soon.

AES Rijndael Cipher explained as a Flash animation
Many years ago I came across a clickable flash animation that explained how the Rijndael cipher works. And even though Rijndael is pure, complex math, the animated visualizations made the whole process so crystal clear that I had to bend down to the floor afterwards to pick up my dropped jaw. Since then I know how powerful animated visualizations can be, even (or rather especially) for abstract and/or complex topics. When I started my Go blog, I knew I had to use animations because they are worth a thousand words. I did the same in my Go videos that you can find over here in my channel, and also in my Go course. This video is a recoding of the flash animation while I click through it. The flash animation is still available at formaestudio.com (link below), but no sane browser would agree to play any flash content anymore, so a video capture is the best we can get. I hope the pace of clicking through the steps is just right for you. NOTE: The video has no audio part. This is not a bug, the Flash animation simply had no sounds. The Rijndael Animation (and another Flash program called Rijndael Inspector): http://www.formaestudio.com/rijndaelinspector/ (c) Enrique Zabala. License terms: "Both these programs are free of use."

Preprocessing involves padding a message, parsing the padded message into m-bit blocks, and setting initialization values to be used in the hash computation. The hash computation generates a message schedule from the padded message and uses that schedule, along with functions, constants, and word operations to iteratively generate a series of hash values.

What is POST-QUANTUM CRYPTOGRAPHY? What does POST-QUANTUM CRYPTOGRAPHY mean? POST-QUANTUM CRYPTOGRAPHY meaning - POST-QUANTUM CRYPTOGRAPHY definition - POST-QUANTUM CRYPTOGRAPHY explanation. 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 Post-quantum cryptography refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against an attack by a quantum computer. This is not true for the most popular public-key algorithms, which can be efficiently broken by a sufficiently large quantum computer. The problem with the currently popular algorithms is that their security relies on one of three hard mathematical problems: the integer factorization problem, the discrete logarithm problem or the elliptic-curve discrete logarithm problem. All of these problems can be easily solved on a sufficiently powerful quantum computer running Shor's algorithm. Even though current, publicly known, experimental quantum computers are too small to attack any real cryptographic algorithm, many cryptographers are designing new algorithms to prepare for a time when quantum computing becomes a threat. This work has gained greater attention from academics and industry through the PQCrypto conference series since 2006 and more recently by several workshops on Quantum Safe Cryptography hosted by the European Telecommunications Standards Institute (ETSI) and the Institute for Quantum Computing. In contrast to the threat quantum computing poses to current public-key algorithms, most current symmetric cryptographic algorithms and hash functions are considered to be relatively secure against attacks by quantum computers. While the quantum Grover's algorithm does speed up attacks against symmetric ciphers, doubling the key size can effectively block these attacks. Thus post-quantum symmetric cryptography does not need to differ significantly from current symmetric cryptography.

https://8gwifi.org/CipherFunctions.jsp Reference book: http://leanpub.com/crypto Computer Security, Cryptography Advanced Encryption Standard AES,fips 197 The Advanced Encryption Standard (AES) specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information. Encryption converts data to an unintelligible form called ciphertext; decrypting the ciphertext converts the data back into its original form, called plaintext. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. aes encryption and decryption aes encryption example aes encryption tutorial aes encryption online aes algorithm, aes encryption explained, aes algorithm tutorial, aes encryption and decryption algorithm, aes encryption algorithm, aes algorithm lecture, aes algorithm example, aes cryptography, aes encryption and decryption algorithm

Storj: Decentralizing Cloud Storage
Storj (pronounced: storage) aims to become a cloud storage platform that can’t be censored or monitored, or have downtime. Storj is a platform, cryptocurrency, and suite of decentralized applications that allows users to store data in a secure and decentralized manner. It uses blockchain features like a transaction ledger, public/private key encryption, and cryptographic hash functions for security. Furthermore, it will be way cheaper (10x-to-100x), faster, and more secure than traditional cloud storage services. Storj is working hard to solve data security issues with the help of its own web app, MetaDisk, and client app, DriveShare. It is the first decentralized, end-to-end encrypted cloud storage that uses blockchain technology and cryptography to secure online files. There is no need to trust a corporation, vulnerable servers, or employees with your files. Storj completely removes trust from the equation. To best protect your data, files are encrypted client-side on users’ computers before they are uploaded. Each file is split up into chunks which are first encrypted and then distributed for storage across the Storj network. The network is comprised of DriveShare nodes run by users around the world who rent out their unused hard drive space in return for Storjcoin X (SJCX). The decentralized aspect of Storj means there are no central servers to be compromised, and because of the use of client-side encryption, only the end-users have access to their unencrypted files and encryption keys.
