Abstract: The security of the block cipher FOX against meet-in-the-middle attack was analyzed. Firstly, 3-round meet-in-the-middle distinguishers was constructed and 6-round meet-in-the-middle attacks for FOX64 and FOX128 was proposed. The two attacks were beter attacks for 6-round FOX64 and FOX128, respectively. Secondly, the meet-in-the-middle distinguisher was extended of FOX128 to 4 rounds and proposed 7-round meet-in-the-middle attack combined with time/memory/data tradeoff. Compared to the currently known attacks on 7-round FOX128, The attack has a greater time and memory complexity, however the data complexity is much smaller.
