Key Exchange
 
03:29
This clip from the 2008 Royal Institution Christmas Lectures shows a simple demonstration of how two people can agree on a secret key, even though all of their communications are carried out in public. In the electronic world, secret key exchange allows computers to communicate securely, and is used, for example, when you give your credit card information to an on-line shop. You can watch the 2008 Royal Institution Christmas Lectures in full at: http://research.microsoft.com/~cmbishop or by visiting the Royal Institution web site. There is a dedicated web site to accompany the 2008 Christmas Lectures, with ten interactive games as well as downloadable PDF instructions for experiments which can be conducted at home or at school: http://www.rigb.org/christmaslectures08

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.

How do two parties exchange keys to communicate securely?
 
04:47
While asymmetric (public-key) encryption does allow two parties to communicate security without exchanging keys, asymmetric encryption requires expensive computation for each message. Symmetric key algorithms are much more efficient. As a result, the two techniques are usually applied to establish and maintain a secure connection. Asymmetric encryption is used to protect the initial part of the connection where symmetric keys are exchanged. Once communicating parties agree on symmetric keys, symmetric encryption is used for the remainder of the communication.

Public Key Encryption (Asymmetric Key Encryption)
 
05:06
In public key encryption, two different keys are used to encrypt and decrypt data.One is the public key and other is the private key. These two keys are mathematically related. They come as a pairs. The public key encryption is also called asymmetric key encryption because two different keys are used. Public key algorithm is used for different purpose from private key algorithm. It is used for verification and authentication. In this video, I will use an example to demonstrate how to use public key.

In this video, we learn how internet encryption works to secure your data. Diffie Hellman is the most popular form of internet encryption. It allows two or more parties to exchange information securely. We look at how it works, in general, and then we look at the specific equations that are behind it. We also discuss downfalls with Diffie Hellman, which now requires 2048 bit keys, and the potential for Elliptic Curve Cryptography.
