An 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. How to thank TFD for its existence?

| 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. |
