Abstract
Aspects of a method and system for protected MAC sequence numbers, as well as secure block acknowledgment (block ACK) with protected MAC sequence number are presented. In one aspect of the system a communicating station (STA) may protect the sequence number (SN) field portion of transmitted protocol data units (PDUs), for example data MAC layer PDUs (MPDUs), or frames. In another aspect of the system, starting sequence number (SSN) information communicated via control frames, such as block acknowledgment request (BAR) and block acknowledgment (BA) frames, may be protected. In another aspect of the system, communicating STAs may exchange management frames to enable the protection of SN information in data MPDUs and/or the protection of SSN values in control MPDUs.
