Random subgroups and analysis of the length-based and quotient attacks

Journal of Mathematical Cryptology, 2008
In this paper we discuss generic properties of “random subgroups” of a given group G. It turns out that in many groups G (even in most exotic of them) the random subgroups have a simple algebraic structure and they “sit” inside G in a very particular way.

Optimizations in Algebraic and Differential Cryptanalysis [PDF]

, 2015
In this thesis, we study how to enhance current cryptanalytic techniques, especially in Differential Cryptanalysis (DC) and to some degree in Algebraic Cryptanalysis (AC), by considering and solving some underlying optimization problems based on the ...

A Chaotic-Initiated Discrete Optimization Framework for Cryptographically Strong AES S-Box Generation

Cybernetics and Information Technologies
Advanced Encryption Standard (AES) security relies on the Substitution box (S-Box), which provides nonlinearity and confusion. Because this algebraic form is fixed, the cipher can be attacked with algebraic and structural cryptanalysis.
