We introduce tuple cryptanalysis, a variant of structural cryptanalysis techniques as square, saturation, integral, internal collision, or multiset cryptanalysis, the main difference being that tuple cryptanalysis considers ordered rather than unordered multisets. This allows cryptanalysts to better trace structural properties within a cipher’s internal state. Unlike previous works that focus o...
In [12], T. Matsumoto and H. Imai designed an asymmetric cryptosystem, called C∗, for authentication, encryption and signature. This C∗ scheme was broken in [13] due to unexpected algebraic properties. In this paper, we study some new “candidate” asymmetric cryptosystems based on the idea of hiding one or two rounds of small S-box computations with secret functions of degree one or two. The pub...
we give a survey of recent applications of group rings to combinatorics and tocryptography, including their use in the di erential cryptanalysis of block ciphers.
