The cipher SHARK. We present the new block cipher SHARK. This cipher combines highly non-linear substitution boxes and maximum distance separable error correcting codes (MDS-codes) to guarantee a good diffusion. The cipher is resistant against differential and linear cryptanalysis after a small number of rounds. The structure of SHARK is such that a fast software implementation is possible, both for the encryption and the decryption. Our C-implementation of SHARK runs more than four times faster than SAFER and IDEA on a 64-bit architecture.
