  MIBS is a light weight block cipher aimed at extremely constrained resources
environments such as RFID tags and sensor networks. In this paper, we focus on
improved key-recovery attacks on reduced-round MIBS with integral and
zero-correlation linear cryptanalysis. By exploring the key-expanding
properties and choosing suitable linear approximations with
zero-correlation,13-round zero-correlation linear cryptanalysis were presented.
Furthermore, we deduced some integral distinguishers from 8-round
zero-correlation linear approximations using the relations between them, and as
applications, we applied these integral distinguishers to the cryptanalysis of
MIBS.
