Abstract

A Korean standard block cipher ARIA is a 128-bit block cipher supporting 128-, 192- and 256-bit secret keys. It is well known that an attacker should obtain at least four consecutive round keys or particular two round keys in order to recover the secret key of ARIA-128. In this paper, we propose the method to recover the secret key by using only the last round key. The proposed method is based on a guess-and-determine attack, which requires the computational complexity of . To our knowledge, this result did not introduced so far.
