Cryptanalysis of loki91

WebJun 20, 1998 · This paper describes LOKI97, a new private key block cipher with 128-bit data and a 256-bit key schedule, which can be initialised by 128, 192, or 256-bit keys. The data computation uses 16 rounds... WebIn cryptography, LOKI89 and LOKI91 are symmetric-key block ciphers designed as possible replacements for the Data Encryption Standard (DES). The ciphers were developed based on a body of work analysing DES, and are very similar to DES in structure. The LOKI algorithms were named for Loki, the god of mischief in Norse mythology.

In 1997, Sakurai and Furuya [320] presented a way to improve the linear cryptanalysis method (in particular, for the LOKI91 cipher) by considering probabilistic behavior of some bits in approximation instead of their fixed values.

It is a member of the LOKI family of ciphers, earlier instances being LOKI89 and LOKI91. LOKI97 was designed by Lawrie Brown, assisted by Jennifer Seberry and Josef Pieprzyk.

Practical examples are the attack of Knudsen and Robshaw [15] against LOKI91 and the one of Shimoyama and Kaneko [28] against DES which both use non-linear approximations.
