Symmetric Key and Public Key Encryption
 
06:45
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.

Learn Public Key Cryptography in just 18 Minutes - Cryptography Tutorial
 
18:07
+++See my latest video: Internet Security or Die+++ https://youtu.be/CzB5n6_pBfk Learn Public Key Cryptography in just 18 Minutes - Cryptography Tutorial In this Cryptography Tutorial, I teach you Public Key cryptography basics. Specifically I’m going to explain to you how the cryptography works, that allows you to do online shopping. We are so used to online shopping, a.k.a. e-commerce, that we take it for granted. But e-commerce would not be possible at all without public key cryptography. Not only will I explained to you the details of public-key cryptography and how that makes e-commerce possible, but I’m going to explain it in 15 minutes, and explain it without math, by using the Blackbox model. IMHO, cryptography basics should not include math. Cryptography explained with math simply muddies the waters to those without extensive math background. Let’s start by taking a brief look at Classic cryptography, which is been around for thousands of years. Classic cryptography is also called secret key cryptography or Symmetric cryptography. A cipher is some sort of a mathematical algorithm that we use to scramble text. In the blackbox model the cipher itself is the blackbox into which we input plaintext and the key. The plaintext is the message that we wish to encrypt and the key is simply a string of numbers, generally binary ones and zeros. The output we get from the blackbox is called ciphertext, which is the plaintext that has been encrypted in such a way that it can only be decrypted by someone that has the same key that originally encrypted the data in the first place. Some examples of Symmetric cryptography that are used today are DES, Triple DES & AES. These are the same as the ciphers used for thousands of years in that the same key encrypts and decrypts them. However the modern algorithm is much stronger. If we use of good cipher such as AES the only way an attacker can decrypt the ciphertext is to try every possible key, called a brute force attack. That is why the longer the key the more security you get. Now supposing Bob wants to buy something on the website Alice.com. He needs to make sure his personal information cannot be seen by anybody eavesdropping on his conversation over the public Internet. At first glance it seems easy enough for Bob to encrypt his plaintext personal information with Symmetric cryptography, using a secret key, send it across the Internet in an encrypted fashion, and then have Alice.com decrypt the information with the same secret key. The problem arises: how do Bob and Alice.com both get the same secret key, while making sure no one else gets the key? The answer is no one has ever thought of a very efficient way. In order to do this, a whole new type of encryption called public key encryption, a.k.a. Asymmetric encryption had to be invented first. In fact it was invented in the 1970s thousands of years after mankind first started using cryptography.

14:14
RSA being a public key crypto-system has two keys, the Public key and the Private key. The Encryption is done using one and the decryption is done using the other. Normally, the encryption is done using the Public key and the decryption is done using the Private key. The RSA modulus (explained below) length is called the key length of the cipher. The currently largest factored prime number had 768 bit. As the security of RSA depends on the factoring problem, using a modulus of 1024 bits is a bare minimum. It is recommended to use at least 2048 bits for good security. 4096 bit is pretty much unbreakable, anything beyond 4096 bits is over the top and would also be painfully slow. #selfhostwcf, #p2pnetworkprogramming,#netcorecommerce

Both Symmetric and Asymmetric key method can be used to secure message. First the message is encrypted with a symmetric key and then before sending the key to other party the key itself is encrypted with other parties public key. The other party on receiving the encrypted message and encrypted key, first decrypts the key with private key and than decrypts the message by using the decrypted key.

AES Encryption 2: AddRoundKey, SubBytes and ShiftRows
 
21:09
In this vid we'll fill out the bodies to three of the steps in AES. These three steps are AddRoundKey, SubBytes and ShiftRows. The remaining steps to AES are rather fiddly, MixColumns and ExpandKey, so we'll look at those separately. I've also taken the opportunity to introduce Galois fields for the AddRoundKey section. AddRoundKey is really just a matter of performing XOR, but it helps to understand Galois fields before we come to the MixColumns step.
