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.

Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a trigger frame addressed to a second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard (such as IEEE 802.11ax or a subsequent IEEE 802.11 standard). Then, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard. When the second electronic device indicates support for the modified response frame during association with the electronic device, the interface circuit may define parameters associated with the modified response frame in an association response.

Abstract: An electronic device (such as an access point) that receives a modified response frame is described. During operation, an interface circuit in the electronic device may provide a management frame addressed to a second electronic device. Then, the interface circuit may provide a trigger frame addressed to the second electronic device, where the trigger frame includes a trigger-frame variant that is compatible with an IEEE 802.11 standard. Next, the interface circuit may receive a modified response frame associated with the second electronic device, where the modified response frame is different from a response frame associated with the trigger frame specified by the IEEE 802.11 standard, and modifications to the modified response frame are specified in the management frame.
