The Data Encryption Standard (DES). As mentioned earlier there are two main types of cryptography in use today - symmet- ric or secret key cryptography and asymmetric or public key cryptography. Symmet- ric key cryptography is the oldest type whereas asymmetric cryptography is only being used publicly since the late

DES is an implementation of a Feistel Cipher. It uses 16 round Feistel structure. The block size is. 64-bit. Though, key length is 64-bit, DES has an effective key length of 56 bits, since 8 of the 64 bits of the key are not used by the encryption algorithm functionascheckbitsonly. General Structure of DES is depicted in the

History of Data Encryption Standard. (DES). • 1967: Feistel at IBM. – Lucifer: block size 128; key size 128 bit. • 1972: NBS asks for an encryption standard. • 1975: IBM developed DES (modification of Lucifer). – block size 64 bits; key size 56 bits. • 1975: NSA suggests modifications. • 1977: NBS adopts DES as encryption
