Jian Liu, Yanjun Li, Runyi Liu, Jian Zou, Zhiqiang Wang
MIBS is a 32-round lightweight block cipher following a Feistel structure with the block length of 64-bit and the key length of 64 or 80 bits. In this paper, the properties of the key scheduling algorithm are investigated and lots of repeated bits among the different round keys are found. Moreover, the optimal guessing order of the unknown key …
