Abstract:

A new 6-round meet-in-the-middle distinguisher was constructed by introducing multiset,making use of properties of the S-box was proposed and the truncated differential characteristic.Based on the distinguisher,a meet-in-the-middle attack on 11-round 3D cipher and the time complexity of recovering the key was about 2329.Furthermore,the data complexity was reduced using the time/memory tradeoff technique.Besides,by utilizing the new distinguisher,the time complexity of 10-round attack on 3D cipher is reduced to 2201.

Key words: block cipher, 3D cipher, meet-in-the-middle attack, precomputation, multiset
