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.

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
