Abstract
A method for communication in a WLAN includes onboarding, authenticating, and configuring respective BSSs of multiple access points in a multi-AP network. Respective cryptographic keys are generated for the multi-AP agents in the network by carrying out a handshaking procedure between the multi-AP controller and the multi-AP agents over the backhaul network. Upon detecting a predefined rekeying event in communications between the multi-AP controller and any given multi-AP agent, a new cryptographic key is generated for the given multi-AP agent by repeating the handshaking procedure, and applying the new cryptographic key in encrypting and authenticating messages following the rekeying event.
