Abstract: Methods, systems and apparatuses for performing a encryption and/or protection of MAC headers and/or control frames are described. A wireless device can determine a randomized MAC address and offset to obfuscate MAC headers and/or control frames, e.g., which can change at different times/intervals. The wireless device can determine an encryption block pattern, which can be based on an encryption key and/or nonce. The wireless device can encrypt the MAC header and/or control frame. Similarly, a receiving device can receive an encrypted MAC header and/or control frame and decrypt it according to corresponding techniques.
