چکیده

In this paper, we present a characteristic set method to solve polynomial equation systems in the finite field F2. Due to the special property of F2, the given characteristic set methods are much more efficient and simpler than the general characteristic set method. We also use our methods to solve equations raised from cryptanalysis of stream ciphers based on nonlinear filter generators.

A new method for accelerating impossible differential cryptanalysis and its application on LBlock

Impossible differential cryptanalysis, the extension of differential cryptanalysis, is one of the most efficient attacks against block ciphers. This cryptanalysis method has been applied to most of the block ciphers and has shown significant results. Using structures, key schedule considerations, early abort, and pre-computation are some common methods to reduce complexities of this attack. In ...

Characteristic set algorithms for equation solving in finite fields

Efficient characteristic set methods for computing solutions of a polynomial equation system in a finite field is proposed. We introduce the concept of proper triangular sets and prove that proper triangular sets are square-free in certain sense. We present an improved algorithm which can be used to reduce the zero set of an equation system in general form as the union of zero sets of proper tr...
