Differential Cryptanalysis of KHF [PDF]
, 1998 Bakhtiari et al recently proposed a fast message authentication primitive called KHF. This paper shows that KHF is highly vulnerable to differential cryptanalysis: it can be broken with about 37 chosen message queries. This suggests that the KHF design should be reconsidered.

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

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 ...

Algorithms for differential cryptanalysis
, 2022 Security in symmetric cryptography seems to be a vague notion for nonspecialists. To simplify the reasoning done by cryptanalysts, a symmetric primitive is secured when no practical attack have been found against it. A large part of the security demonstration of a primitive consists in trying every classical attack against the studied primitives.

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

Revisiting the shuffle of generalized Feistel structure
CybersecurityThe Generalized Feistel Structure ( $$\texttt{GFS}$$ GFS ) is one of the most widely used frameworks in symmetric cipher design. In FES 2010, Suzaki and Minematsu strengthened the cryptanalysis security of $$\texttt{GFS}$$ GFS by searching for shuffles ...

Quantum impossible differential and truncated differential cryptanalysis
, 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.
