It is particularly optimized for hardware implementation where the expected rate is several Gbps on a small dedicated chip working at 30 MHz. 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.text::conference output::conference proceedings::conference paper
