Abstract
A method of retrieving security information in a media access control (MAC) header by a wireless station may include receiving a data unit, such as a protocol data unit (PDU), from a remote wireless station. The PDU may include the MAC header. The method may also include reading two encryption key sequence (EKS) bits in the MAC header that denote both whether the data unit is encrypted and a position in an encryption key sequence for the data unit.
