  • Mac header protection with preexisting keys
    Patent number: 12621139
    Abstract: The technical solutions are directed to MAC address protection for frame integrity verification. A sender device can compute, using a temporal key (TK) programmed in hardware, a first key for a body of a frame and a second key for a header of the frame, different from the first key. The sender can encrypt the body of the frame at a machine access control (MAC) layer using the first key and the header of the frame at the MAC layer using the second key. The sender can compute a first MIC of the encrypted frame using the first key and a second MIC of a content of the header at the MAC layer using the second key. The sender can transmit the frame with the first MIC and the second MIC to a receiver configured to determine integrity of the header of the frame based on the second MIC.
