Abstract. PRESENT is a hardware-oriented block cipher suitable for resource constrained environment. In this paper we analyze PRESENT by the multidimensional linear cryptanalysis m...
Abstract. In this paper, we present a new technique for Matsui's algorithm 2 using multidimensional linear approximation. We show that the data complexity of the attack can be...
Differential cryptanalysis analyzes ciphers by studying the development of differences during encryption. Linear cryptanalysis is similar but is based on studying approximate linea...
Matsui's linear cryptanalysis for iterated block ciphers is generalized by replacing his linear expressions with I O sums. For a single round, an I O sum is the XOR of a balan...
