Many popular stream ciphers apply a filter/combiner to the state of one or several LFSRs. Algebraic attacks on such ciphers [10, 11] are possible, if there is a multivariate relat...
ABC v3 is a stream cipher proposed as a candidate to ECRYPT Estream Project which enters the second evaluation phase. Its key length is 128 bits. In this paper, We show that, ther...
In this paper we propose several efficient algorithms for assessing the resistance of Boolean functions against algebraic and fast algebraic attacks when implemented in LFSRbased s...

Abstract. This paper describes new methods for fast correlation attacks, based on the theory of convolutional codes. They can be applied to arbitrary LFSR feedback polynomials, in ...
