Algoritmo de
cifra basado en un secreto compartido (clave). Cifra el texto en bloques de 128
bits. Utiliza claves de
128, 192 o 256 bits.
In cryptography,
Camellia is a block cipher that has been evaluated favorably by several
organisations, including the European Union's NESSIE project (a selected
algorithm), and the Japanese CRYPTREC project (a recommended algorithm). The
cipher was developed jointly by Mitsubishi and NTT in 2000, and has similar
design elements to earlier block ciphers (MISTY1 and E2) from these companies.
Camellia has a
block size of 128 bits, and can use 128-bit, 192-bit or 256-bit keys the same interface as the Advanced Encryption
Standard.
