Claim 14:
15. A non-transitory computer readable storage medium comprising instructions that when executed configure one or more processors to perform operations comprising:
receiving, from a wireless client device, a first association request to associate to a wireless network, the wireless client device identified by the association request via a first device address;
rejecting, based on the first device address, the first association request;
transmitting, to the wireless client device, and based on the rejecting, a security association (SA)-query request message;
receiving, from the wireless client device, a SA-query response message;
decoding the SA-query response message to identify a mapping of the first device address to a stable device address;
storing the mapping;
receiving, from the wireless client device, a second association request, the wireless client device identified by the second association request via the first device address;
accepting, based on the stored mapping, the second association request; and
tunneling data communication between an access point and the wireless client device,
wherein a four-way handshake is performed between the wireless client device and the access point after each of the first associating and the second associating.
