Algoritmo de cifra basado en un secreto compartido (clave). Cifra el texto en bloques de 64 bits. Utiliza claves de 128 bits.

(en) KASUMI

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.
