Probabilistic Algebraic Attacks

, 2005
This paper investigates a probabilistic algebraic attack on LFSR-based stream ciphers. We consider two scenarios (S3a and S3b) proposed by Meier et al. at Eurocrypt 2004. In order to derive the probability in this new algebraic attack, we quantify the distance between a Boolean function and a function with annihilator of a certain degree.

Some results on fast algebraic attacks and higher-order non-linearities

IET Information Security, 2012
In this study, the authors investigate the resistance of Boolean functions against fast algebraic attacks and deduce a bound between fast algebraic immunity and higher-order non-linearity (it is the first time that a bound between these two cryptographic

Algebraic Attacks on Round-Reduced Keccak

IACR Cryptology ePrint Archive, 2021
Since Keccak was selected as the SHA-3 standard, both its hash mode and keyed mode have attracted lots of third-party cryptanalysis. Especially in recent years, there is progress in analyzing the collision resistance and preimage resistance of round-reduced Keccak.

Algebraic Attacks on the Courtois Toy Cipher

Cryptologia, 2008
This article presents and discusses some of the most important algebraic attack algorithms (F4, DR, XL) and employs them against Courtois' toy cipher (CTC). Also, CTC is attacked using more specialized algorithms and the experimental results of these attacks are presented.
