In Cryptography , MARS is a Block Cipher which was IBM 's submission to the Advanced Encryption Standard Process (AES). MARS was selected as a finalist. The design team included Don Coppersmith who had been involved in the creation of the previous Data Encryption Standard (DES) twenty years earlier. MARS has a 128-bit Block Size and a variable Key Size of between 128 and 448 bits (in 32-bit increments). Unlike most block ciphers, MARS has a heterogeneous structure: several rounds of a cryptographic core are "jacketed" by unkeyed mixing rounds. EXTERNAL LINKS |
