This article describes new theoretical results concerning the general behavior of a Feedback with Carry Shift Register (FCSR) automaton. They help to better understand how the init...
GOST is a well known block cipher which was developed in the Soviet Union during the 1970’s as an alternative to the US-developed DES. In spite of considerable cryptanalytic eff...
Abstract. In this paper, we study GF-NLFSR, a Generalized Unbalanced Feistel Network (GUFN) which can be considered as an extension of the outer function FO of the KASUMI block cip...
