Improved Search for Integral, Impossible-Differential and Zero-Correlation Attacks: Application to Ascon, ForkSKINNY, SKINNY, MANTIS, PRESENT and QARMAv2 [PDF]
, 2023 Integral, impossible-differential (ID), and zero-correlation (ZC) attacks are three of the most important attacks on block ciphers. However, manually finding these attacks can be a daunting task, which is why automated methods are becoming increasingly ...

Improving the Security Bounds against Differential Attacks for Pholkos Family
IEICE Transactions on Fundamentals of Electronics Communications and Computer SciencesSUMMARY At CT-RSA 2022, Bossert et al. proposed Pholkos family, an efficient large-state tweakable block cipher. In order to evaluate the security of differential attacks on Pholkos , they obtained the lower bounds for the number of active S-boxes for ...

Computing the Differential Probability of a Word-Based Block Cipher
CryptographyDifferential cryptanalysis is one of the fundamental cryptanalysis techniques to evaluate the security of the block cipher. In many cases, resistance to differential cryptanalysis is proven through the upper bound of the differential characteristic ...

Related-Tweakey Impossible Differential Attack on Reduced-Round Deoxys-BC-256 [PDF]
, 2018 Deoxys-BC is the internal tweakable block cipher of Deoxys, a third-round authenticated encryption candidate at the CAESAR competition. In this study, by adequately studying the tweakey schedule, we seek a six-round related-tweakey impossible ...

Chosen-Key Distinguishing Attacks on Full AES-192, AES-256, Kiasu-BC, and More [PDF]
, 2023 At CRYPTO 2020, Liu et al. find that many differentials on Gimli are actually incompatible. On the related-key differential of AES, the incompatibilities also exist and are handled in different ad-hoc ways by adding respective constraints into the ...
