Abstract
In one embodiment, each security protocol supplicant in a computer network determines its group temporal key (GTK) state, and exchanges the GTK state with one or more neighbor supplicants in the computer network. Based on the exchange, a supplicant may determine whether any inconsistencies exist in its GTK state, and in response to any inconsistencies in the GTK state, may perform a GTK state synchronization with a security protocol authenticator by indicating to the authenticator what is needed to resolve the inconsistent GTK state at the particular supplicant. In another embodiment, the authenticator, which is configured to not store per-supplicant GTK state, may transmit beacons containing GTK identifiers (IDs) of GTKs currently enabled on the authenticator, and also responds to supplicants having inconsistent GTK states with one or more needed GTKs as indicated by the supplicants.
