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.

Efficient MILP Modelings for Sboxes and Linear Layers of SPN ciphers
IACR Transactions on Symmetric Cryptology, 2020 Mixed Integer Linear Programming (MILP) solvers are regularly used by designers for providing security arguments and by cryptanalysts for searching for new distinguishers.

Accurate Estimate of the Advantage of Impossible Differential Attacks
IACR Transactions on Symmetric Cryptology, 2017 Impossible differential attacks, which are taking advantage of differentials that cannot occur, are powerful attacks for block cipher primitives. The power of such attacks is often measured in terms of the advantage — number of key-bits found during the ...

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.

Integral and impossible‐differential attacks on the reduced‐round Lesamnta‐LW‐BC
IET Information Security, 2022 Lesamnta‐LW‐BC is the internal block cipher of the Lesamnta‐LW lightweight hash function, specified in ISO/IEC 29192‐5:2016. It is based on the unbalanced Feistel network and Advanced Encryption Standard round function.

Impossible differential cryptanalysis of SPN ciphers
IET Information Security, 2011 Impossible differential cryptanalysis is a very popular tool for analysing the security of modern block ciphers and the core of such attack is based on the existence of impossible differentials. Currently, most methods for finding impossible differentials are based on the miss-in-the-middle technique and they are very ad hoc. In this study, the authors
