摘要:This paper describes a meet-in-the-middle (MITM) attack against the round reduced versions of the block cipher mCrypton-64/96/128. We construct a 4-round distinguisher and lower the memory requirement from 2(100) to 2(44) using the differential enumeration technique. Based on the distinguisher, we launch a MITM attack on 7-round mCrypton64/96/128 with complexities of 2(44) 64-bit blocks and 2(57) encryptions. Then we extend the basic attack to 8 rounds for mCrypton-128 by adding some key-bridging techniques. The 8-round attack on mCrypton-128 requires a time complexity 2(100) and a memory complexity 2(44). Furthermore, we construct a 5-round distinguisher and propose a MITM attack on 9-round mCrypton-128 with a time complexity of 2(115) encryptions and a memory complexity of 2(113) 64-bit blocks.
