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.

Impossible Differential Cryptanalysis of Zodiac [PDF]
, 2002 We discuss the impossible differential cryptanalysis of the blockcipher Zodiac. The main design principles of Zodiac are simplicity and efficiency. However the diffusion layer in its round function is too simple to offer enough security. An impossible differential cryptanalysis is a proper method to attack the weakness of Zodiac.

Quantum impossible differential and truncated differential cryptanalysis
CoRR, 2017 Traditional cryptography is suffering a huge threat from the development of quantum computing. While many currently used public-key cryptosystems would be broken by Shor's algorithm, the effect of quantum computing on symmetric ones is still unclear. The security of symmetric ciphers relies heavily on the development of cryptanalytic tools.
