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. Like DES, LOKI97 is a …
WebIn 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. See also [ 14, 203, 283, 324 ]. WebFollowing the publication of LOKI89, information on the new differential cryptanalysis became available, as well as some early analysis results by (Knudsen 1993a). This resulted in the design being changed to become LOKI91. LOKI91. LOKI 91 was designed in response to the attacks on LOKI89 (Brown et. al., 1991).
Weborder to avoid some variant forms of differential cryptanalysis, permu tation P needs to be chosen to prevent easy propagation of a constant XOR value back into the same S-box. We redesign the LOKI cipher to form LOKI91, to illustrate these results, as well as to correct the key schedule to remove the formation of equivalent keys. We conclude WebSep 1, 2024 · The result shows that the MISTY1 cipher can be distinguishable from an ideal cipher in terms of related-key amplified boomerang cryptanalysis, and users should be very careful when using MISTY1 for a full security in relevant application situations.

WebNov 22, 2024 · Cryptanalysts are code breakers. The term “cryptanalysis” comes from the Greek words kryptós (“hidden”) and analýein (“to analyze”).

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.
