Michael is the Message Integrity Code adapter by the TKIP standard. Michael is actually a weak code which uses simple additions and shift operation which are computationally less expensive, but strong enough as a intermediate solution from WEP. Michael was chosen as MIC in TKIP, so that the already deployed low end Access Points can also be software upgraded to TKIP without any hardware change. This video explains the working of MIC in TKIP.
