Abstract

This paper presents a new block cipher which offers good encryption rate on any platform. It is particularly optimized for hardware implementation where the expected rate is several Gbps on a small dedicated chip working at 30MHz. Its design combines up to date state of the art concepts in order to make it (hopefully) secure: diffusion network based on the Fast Fourier Transform, multipermutations, highly nonlinear confusion boxes.
