Which mechanism in WPA prevents the altering and replay of data packets?

Message Integrity Check (MIC), also known as Michael, is responsible for the protection of messages by including an integrity check that the other side can verify. Temporal Key Integrity Protocol (TKIP) was used as an encryption protocol for WPA as a quick replacement of Wired Equivalent Privacy (WEP). Advanced Encryption Standard (AES) is an encryption protocol first introduced with WPA2. A cyclic redundancy check (CRC) is a simple calculation to assure that data is not damaged in transit.
