In cryptography, KASUMI, also termed A5/3, is a block cipher used in the confidentiality (''f8'') and integrity algorithms (''f9'') for 3GPP mobile phone. 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, an existing algorithm, MISTY1, was selected by SAGE and slightly optimised for implementation in hardware. Hence, both MISTY1 and KASUMI are very similar — ''kasumi'' is the Japanese language word for "misty" — and the cryptanalysis of one is likely to be readily adaptable to the other. KASUMI has a block size (cryptography) of 64 bits and a key size of 128 bits. It is a Feistel cipher with eight rounds, and like MISTY1 and MISTY2, it has a recursive structure, with subcomponents also having a Feistel-like form. In 2001, an impossible differential attack on six rounds of KASUMI was presented by Kühn (2001). ==See also== * A5/1 and A5/2 ==References== * ETSI/SAGE, "KASUMI Specification, Part of the Specification of the 3GPP Confidentiality and Integrity Algorithms", 1999. * Kühn, U.
