CRYPTON [8] is a 12-round block cipher proposed as an AES candidate by C.H. Lim in 1998. C.H. Lim also introduced in 1999 [9] a modified CRYPTON with a new key schedule and new S-boxes. This paper presents truncated differential attacks on the modified CRYPTON up to 8 out of its 12 rounds. These are the best known attacks for this cipher.
