Device address rotation management protocol for a wireless local area network
Techniques herein facilitate a device address rotation management protocol that may be implemented for a wireless local area network (WLAN), which can be used to influence when wireless client devices or stations may rotate their Media Access Control (MAC) addresses, how to perform such rotations, and/or the like. In one example, a method may include providing, by an access point (AP), a first communication indicating that the AP supports a MAC address rotation management protocol; obtaining, by the AP, a second communication from a wireless station (STA) indicating that the STA intends to perform a MAC address rotation; and transmitting, by the AP, a third communication to influence the MAC address rotation of the STA, the third communication comprising a rotation status indicator and timing information.
1. A method comprising:
providing, by an access point (AP), a first communication indicating that the AP supports a Media Access Control (MAC) address rotation management protocol;
obtaining, by the AP, a second communication from a wireless station (STA) indicating that the STA intends to perform a MAC address rotation; and
transmitting, by the AP, a third communication to influence the MAC address rotation of the STA, the third communication comprising a rotation status indicator and timing information, wherein the timing information indicates a schedule for the STA to perform the MAC address rotation.
2. The method of claim 1 , wherein the second communication is an informational query included in a first Robust Action frame obtained from the STA and the third communication is a request included in a second Robust Action frame transmitted by the AP.
3. The method of claim 2 , wherein each of the first Robust Action frame and the second Robust Action frame comprises an identifier indicating that the first Robust Action frame and the second Robust Action frame are each associated with the MAC address rotation management protocol.
4. The method of claim 1 , wherein the timing information further includes a delay timer value indicating when the STA is to perform the MAC address rotation.
5. The method of claim 1 , wherein the timing information further includes a rotation timer value indicating a time interval for the STA to perform the MAC address rotation.
6. The method of claim 1 , wherein the timing information further includes a comeback timer value indicating that the STA is to send a fourth communication indicating that the STA intends to perform the MAC address rotation upon expiration of the comeback timer value.
7. The method of claim 1 , wherein the timing information further includes a comeback timer value indicating that the STA is to await an instruction from the AP before performing the MAC address rotation.
8. The method of claim 1 , wherein upon the second communication obtained from the STA comprising a rotation schedule including a rotation timer value that the STA intends to utilize to perform the MAC address rotation, at least one of the rotation status indicator and the timing information of the third communication indicates whether the AP is capable of supporting the rotation schedule or is not capable of supporting the rotation schedule.
9. The method of claim 8 , wherein the timing information is one of a reserved value indicating that either that the AP is capable or not capable of supporting the rotation schedule or is an alternate rotation timer value.
10. The method of claim 1 , wherein the timing information indicates a time period window within which the STA is to generate a random number that identifies when the STA is to perform the MAC address rotation.
11. The method of claim 1 , wherein the rotation status indicator indicates a recommendation for the STA to proceed or not to proceed with the MAC address rotation.
12. The method of claim 11 , wherein upon the rotation status indicator indicating the recommendation for the STA to not to proceed with the MAC address rotation, the third communication further indicates a reason for the recommendation for the STA to not to proceed with the MAC address rotation.
13. The method of claim 12 , further comprising:
upon obtaining by the AP an authentication request, an association request, or a reassociation request from the STA indicating that the STA has performed the MAC address rotation, rejecting the authentication request, the association request, or the reassociation request.
14. The method of claim 12 , further comprising:
determining, by the AP, that the STA can proceed with the MAC address rotation; and
transmitting, by the AP, an unsolicited fourth communication comprising another rotation status indicator and other timing information that seeks to influence the MAC address rotation of the STA.
15. One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor of an access point (AP), cause the processor to perform operations, comprising:
providing a first communication indicating that the AP supports a Media Access Control (MAC) address rotation management protocol;
obtaining a second communication from a wireless station (STA) indicating that the STA intends to perform a MAC address rotation; and
transmitting a third communication to influence the MAC address rotation of the STA, the third communication comprising a rotation status indicator and timing information, wherein the timing information indicates a schedule for the STA to perform the MAC address rotation.
16. The media of claim 15 , wherein the timing information further includes a delay timer value indicating when the STA is to perform the MAC address rotation.
17. The media of claim 15 , wherein the timing information further includes a rotation timer value indicating a time interval for the STA to perform the MAC address rotation.
18. An apparatus comprising:
at least one memory element for storing data; and
at least one processor for executing instructions associated with the data, wherein executing the instructions causes the apparatus to perform operations, comprising:
providing a first communication indicating that the apparatus supports a Media Access Control (MAC) address rotation management protocol;
obtaining a second communication from a wireless station (STA) indicating that the STA intends to perform a MAC address rotation; and
transmitting a third communication to influence the MAC address rotation of the STA, the third communication comprising a rotation status indicator and timing information, wherein the timing information indicates a schedule for the STA to perform the MAC address rotation.
19. The apparatus of claim 18 , wherein the timing information further includes a delay timer value indicating when the STA is to perform the MAC address rotation.
20. The apparatus of claim 18 , wherein the timing information further includes a rotation timer value indicating a time interval for the STA to perform the MAC address rotation.
