Webcryptanalysis but vulnerable to their generalization. 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. In [8], Harpes and Massey generalize the results of [7] by considering par-titions pairs of the input and output spaces. WebIn section 2 we do differential cryptanalysis of LOK191 and show that there is no characteristic with a probability high enough to do a successful differential attack. …

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. Contents LOKI89 WebIn this paper we examine the redesign of LOKI, LOKI91 proposed by Brown et al. First it is shown that there is no characteristic with a probability high enough to do a successful …
WebTemplate:Infobox block cipher In cryptography, LOKI97 is a block cipher which was a candidate in the Advanced Encryption Standard competition. 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.
