block cipherAn encryption method that processes the input stream as groups of bytes that are fixed in size, typically 64, 128 or 256 bits long. The state of a block cipher is reset before processing each block. The DES and AES algorithms are examples of block ciphers (see DES and AES). Contrast with stream cipher. block cipher [′bläk ‚sī·fər] (communications) A cipher that transforms a string of input bits of fixed length into a string of output bits of fixed length.

Camellia is a 128-bit block cipher (with allowable key lengths of 128, 192, and 256 bits) that was jointly developed by NTT and Mitsubishi in 2000. A symmetric key block cipher algorithm, such as the Data Encryption Standard (DES) specified in Federal Information Processing Standard (FIPS) 46-3 and the proposed Advanced Encryption Standard (AES), are implemented in various modes, depending on specific applications. AES is a block cipher adopted as an encryption standard by the U. |
