Abstract. In this paper, we demonstrate that the linear hull effect is significant for the Q cipher. The designer of Q performs preliminary linear cryptanalysis by discussing linear characteristics...

A block cipher, which is an important cryptographic primitive, is a bijective mapping from {0, 1} N to {0, 1} N (N is called the block size), parameterized by a key. In the true random cipher, each...

In [3], we present a new algorithm for computing an upper bound on the maximum average linear hull probability (MALHP) for the SPN symmetric cipher structure, a value required to make claims about...

Abstract. In this paper, we demonstrate that the linear hull effect is significant for the Q cipher. The designer of Q performs preliminary linear cryptanalysis by discussing linear characteristics...
Modeling linear characteristics of substitution-permutation networks (2000)
Liam Keliher, Henk Meijer, Stafford Tavares
Abstract. In this paper we present a model for the bias values associated with linear characteristics of substitution-permutation networks (SPN's). The first iteration of the model is based on...
