Abstract

SEED is a 128-bit block cipher with a 128-bit secret key. Since it supports only a 128-bit secret key, it is difficult to apply this algorithm to various environments. In this paper, we propose SEED-192/256 which support 192/256-bit secret keys, respectively. Also we evaluate the security these algorithms against well-known attacks and the software performance of them on PC environments.
