Exact Formula for RX-Differential Probability Through Modular Addition for All Rotations

IACR Transactions on Symmetric Cryptology
This 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

Algebraic Precomputations in Differential and Integral Cryptanalysis [PDF]

, 2010
International audienceAlgebraic cryptanalysis is a general tool which permits one to assess the security of a wide range of cryptographic schemes. Algebraic techniques have been successfully applied against a number of multivariate schemes and stream ...

Subspace Trail Cryptanalysis and its Applications to AES

IACR Transactions on Symmetric Cryptology, 2017
We introduce subspace trail cryptanalysis, a generalization of invariant subspace cryptanalysis. With this more generic treatment of subspaces we do no longer rely on specific choices of round constants or subkeys, and the resulting method is as such a ...

Linear and Differential Cryptanalysis of SHA-256 [PDF]

, 2005
The one-way hash function plays an important role in digital signatures and message authentication from the viewpoint of security. No effective attacking method has been discovered to the algorithm of hash function standard.

Security against differential and linear cryptanalysis for general SPT models

Tongxin xuebao, 2012
To use SP network in stream ciphers safely and efficiently,the ability against differential and linear cryptanalysis of SPT models was studied,where S and T denote different layers for substitution,in which compression could be achieved,and P denotes the

XSL Block Ciphers’ Key-schedules with Resistance to Differential Cryptanalysis

Безопасность информационных технологий, 2014
The paper discusses the resistance of XSL block ciphers to differential cryptanalysis. AES-like block ciphers with alternative key-schedules (increased performance and density) are given as an example.

A New (Related-Key) Neural Distinguisher Using Two Differences for Differential Cryptanalysis

IET Information Security
At CRYPTO 2019, Gohr showed the significant advantages of neural distinguishers over traditional distinguishers in differential cryptanalysis. At fast software encryption (FSE) 2024, Bellini et al.
