Abstract. A system of Boolean equations is called sparse if each equation depends on a small number of variables. Finding efficiently solutions to the system is an underlying hard ...
In this paper we consider an attack on the SIGABA cipher under the assumption that the largest practical keyspace is used. The attack highlights various strengths and weaknesses o...
This paper reports on an improvement of Matsui’s linear cryptanalysis that reduces the complexity of an attack with algorithm 2, by taking advantage of the Fast Fourier Transform...
Abstract. GOST 28147-89 is a well-known block cipher and the official encryption standard of the Russian Federation. Its large key size of 256 bits at a particularly low implementa...
Although many strong cryptanalytic tools exploit weaknesses in the data-randomizinig part of a block cipher, relatively few general tools for cryptanalyzing on the other part, the ...
