In this paper, we describe the design of a new family of block ciphers based on a Lai-Massey scheme, named FOX. The main features of this design, besides a very high security level...
Linear cryptanalysis, along with differential cryptanalysis, is an important tool to evaluate the security of block ciphers. This work introduces a novel extension of linear crypt...
In this paper we present a new 128-bit block cipher called Square. The original design of Square concentrates on the resistance against dierential and linear cryptanalysis. Howeve...
For years, the cryptographic community has searched for good nonlinear functions. Bent functions, almost perfect nonlinear functions, and similar constructions have been suggested ...
Abstract. This paper presents xmx, a new symmetric block cipher optimized for public-key libraries and microcontrollers with arithmetic coprocessors. xmx has no S-boxes and uses on...
