MIBS is a lightweight block cipher for extremely constrained environments such as RFID tags and sensor networks. The MIBS algorithm's ability to resist zero correlation-integral analysis was evaluated. An 8-round zero corre-lation l
inear distinguisher of MIBS was given. Then
a 8-round distinguisher of MIBS was founded by using relationship between zero-correlation linear distinguisher and integral distinguisher. Finally
considering the symmetrical structure of the MIBS and using the partial-sum technique
it applied integral attack to 10 and 12 rounds of MIBS-80. The time com-plexities of 10 and 12 round attack on MIBS-80 are 2
27.68
and 2
48.81
. The data complexity is 2
