An apparatus including a key mixing circuit, an input circuit, and a decapsulation circuit. The key mixing circuit generates a plurality of seeds, each based on a predetermined temporal key, a transmitter MAC address, and a predetermined start value for a Temporal Key Integrity Protocol (TKIP) Sequence Count (TSC). The input circuit receives a message including the transmitter MAC address and the predetermined start value. The key mixing circuit generates the plurality of seeds based on the message. The input circuit receives a plurality of encapsulated MAC Payload Data Units (MPDUs). The input circuit receives the message before receiving the plurality of encapsulated MPDUs. The decapsulation circuit decapsulates each of the plurality of encapsulated MPDUs using one of the plurality of seeds that was generated based on the value for the TSC in the respective one of the N encapsulated MPDUs. |
