Distinguishers on round-reduced AES have attracted considerable attention in the recent
years. While the number of rounds covered in key-recovery attacks did not increase …

Cryptanalysis is the investigation of cipher content, ciphers and cryptosystems with the point
of seeing how they work and finding and improving procedures for crushing or debilitating …

Tweakable block ciphers (TBCs) have been established as a valuable replacement for many
applications of classical block ciphers. While several dedicated TBCs have been proposed …

Abstract The security of Advanced Encryption Standard (AES) is one of the most important
issues in cryptanalysis. In ToSC 2020, Bao et al. proposed an open question about the …

We revisit the different approaches used in the literature to estimate the data complexity of
distinguishing attacks on stream ciphers and analyze their inter-relationships. In the process …

This work considers statistical analysis of attacks on block cyphers using several linear
approximations. A general and unified approach is adopted. To this end, the general key …

This work studies the success probability of key recovery attacks based on using a single
linear approximation. Previous works had analysed success probability under different …

Statistical analysis of attacks on block ciphers have mostly used normal approximations. A
few recent works have proposed doing away with normal approximations and instead use …

Предложен метод получения нижних границ информационной сложности
статистических атак на блочные или поточные шифры. Метод основан на применении …

The log-likelihood ratio (LLR) and the chi-squared distribution based test statistics have
been proposed in the literature for performing statistical analysis of key recovery attacks on …
