DES also known as Data Encryption Standard algorithm is one of the most famous and widely studied algorithm and is very important to study especially if you are a Computer Science or Information Technology student. We will also study and understand the variations of DES that is the Types of DES. Types of DES - 1. Double DES 2. Triple DES 2.1 Triple DES with 3 Keys 2.2 Triple DES with 2 Keys Data Encryption Standard Algorithm(DES) - 1. The Data Encryption Standard (DES) was developed in the 1970s by the National Bureau of Standards (NBS)with the help of the National Security Agency (NSA). 2. DES is a block cipher. It encrypts data in block size of 64 bits each. 3. It produces 64 bit of cipher text 4. Same algorithm and key are used for encryption and decryption. 5. The key length is 56 bits. The key originally consists of 64 bits; however, only 56 of these are actually used by the algorithm. Eight bits are used solely for checking parity, and are thereafter discarded. Hence the effective key length is 56 bits. 6. Consists of 16 steps, each of which is called as a round. Each round performs the steps of substitution and transposition DES is Based on two fundamental attributes: 1. Substitution - also called as confusion 2. Transposition - also called as diffusion Complete Network Security / Information Security Playlist - https://www.youtube.com/watch?v=IkfggBVUJxY&list=PLIY8eNdw5tW_7-QrsY_n9nC0Xfhs1tLEK Download my FREE Network Security Android App - https://play.google.com/store/apps/details?id=com.intelisenze.networksecuritytutorials Simple Snippets Official Website - http://simplesnippets.tech/ Simple Snippets on Facebook - https://www.facebook.com/simplesnippets/ Simple Snippets on Instagram - https://www.instagram.com/simplesnippets/ Simple Snippets on Twitter - https://twitter.com/simplesnippet Simple Snippets Google Plus Page - https://plus.google.com/+SimpleSnippets Simple Snippets email ID - simplesnippetsinfo@gmail.com For More Technology News, Latest Updates and Blog articles visit our Official Website - http://simplesnippets.tech/ #DES #DataEncryptionStandard #NetworkSecurity
