摘要:
In this paper we present an attack on a reduced round version of CRYPTON. The attack is based on the dedicated SQUARE attack. We explain why the attack also works on CRYPTON and prove that the entire 256-bit user key for 6 rounds of CRYPTON can be recovered with a complexity of 2(56) encryptions, whereas for SQUARE 2(72) encryptions are required to recover the 128-bit user key.
