| Abstract: | 3D cipher is a new block cipher proposed in CANS2008, it uses a 3-dimensional state. This paper introduces a new 6-round meet-in-the-middle distinguisher and a new attack on 10-round 3D cipher. The new attack requires a data complexity of about 2128 chosen plaintexts and a time com- plexity of 232214 10-round 3D encryptions. Compared with the previous published cryptanalytic re- suit, the attack reduces the time complexity and precalculation complexity efficiently. |
