Algoritmo de
cifra basado en un secreto compartido (clave). Cifra el texto en bloques de 64
bits. Utiliza claves de 128 bits.
In cryptography, KASUMI, also
termed A5/3, is a block cipher used in the confidentiality (f8) and integrity
algorithms (f9) for 3GPP mobile communications. A number of serious weaknesses
in the cipher have been identified.
KASUMI was designed by the
Security Algorithms Group of Experts (SAGE), part of the European standards
body ETSI. Rather than invent a cipher from scratch, SAGE selected an existing
algorithm, MISTY1, and optimised it slightly for implementation in hardware.
Hence, MISTY1 and KASUMI are very similar
kasumi () is the Japanese word for "mist" and the cryptanalysis of one is likely to be
readily adaptable to the other. KASUMI maintains an efficient implementation in
software.
