Impossible differential cryptanalysis of MARS‐like structures
IET Information Security, 2015 The MARS‐like structure is a generalised Feistel structure. Unified impossible differential (UID) method is an effective method to discover impossible differential characteristics for block cipher structures. In this study, for a specific kind of MARS‐like structure, the authors use UID to show that when n

Impossible Differential Cryptanalysis of CLEFIA [PDF]
IACR Cryptol. ePrint Arch., 2008 This paper reports impossible differential cryptanalysis on the 128-bit block cipher CLEFIA that was proposed in 2007, including new 9-round impossible differentials for CLEFIA, and the result of an impossible differential attack using them. For the case of a 128-bit key, it is possible to apply the impossible differential attack to CLEFIA reduced to ...

On the Complexity of Impossible Differential Cryptanalysis [PDF]
Security and Communication Networks, 2018 While impossible differential attack is one of the most well-known and familiar techniques for symmetric-key cryptanalysts, its subtlety and complicacy make the construction and verification of such attacks difficult and error-prone. We introduce a new set of notations for impossible differential analysis.

Cybersecurity, 2021 In this paper, we greatly increase the number of impossible differentials for SIMON and SIMECK by eliminating the 1-bit constraint in input/output difference, which is the precondition to ameliorate the complexity of attacks.
