Mix-Basis Geometric Approach to Boomerang Distinguishers
IACR Transactions on Symmetric CryptologyDifferential cryptanalysis relies on assumptions like Markov ciphers and hypothesis of stochastic equivalence. The probability of a differential characteristic estimated by classical methods is the key-averaged probability under the two assumptions ...

A Fast Search Method for 3‐Share Second‐Order Masking Schemes for Lightweight S‐Boxes
IET Information Security, Volume 2025, Issue 1, 2025.Masking schemes are widely adopted strategies for countering side‐channel analysis (SCA) attacks. The initial hardware masking strategy, threshold implementation (TI), provides robust security against glitches in hardware platforms. The minimum number of shares required for a TI scheme depends not only on the desired security order but also on the ...

Impossible Differential Cryptanalysis of 8-Round Deoxys-BC-256
IEEE Access, 2018 Deoxys is a third-round candidate of the CAESAR authenticated encryption competition. In this paper, we present the first cryptanalysis of Deoxys in the single-key model.

Further Results of the Cryptographic Properties on the Butterfly Structures
, 2016 Recently, a new structure called butterfly introduced by Perrin et at. is attractive for that it has very good cryptographic properties: the differential uniformity is at most equal to 4 and algebraic degree is also very high when exponent $e=3$.

Multiple Differential Cryptanalysis: Theory and Practice [PDF]
, 2011 Differential cryptanalysis is a well-known statistical attack on block ciphers. We present here a generalisation of this attack called multiple differential cryptanalysis. We study the data complexity, the time complexity and the success probability of such an attack and we experimentally validate our formulas on a reduced version of PRESENT.

Exact Formula for RX-Differential Probability Through Modular Addition for All Rotations
IACR Transactions on Symmetric CryptologyThis work presents an exact and compact formula for the probability of rotation-xor differentials (RX-differentials) through modular addition, for arbitrary rotation amounts, which has been a long-standing open problem. The formula comes with a rigorous

A note on some algebraic trapdoors for block ciphers
, 2018 We provide sufficient conditions to guarantee that a translation based cipher is not vulnerable with respect to the partition-based trapdoor. This trapdoor has been introduced, recently, by Bannier et al.
