The CS2 Block Cipher

Tom St Denis

Abstract: In this paper we describe our new CS$^2$ block cipher which is an extension of the original CS-Cipher. Our new design inherits the efficiency of the original design while being upgraded to support a larger block size as well as use a slightly improved substitution box. We prove that our design is immune to differential and linear cryptanalysis as well as argue it resists several other known attacks.
