Abstract:
1. A method, comprising: determining, by a particular security protocol supplicant in a computer network, a group temporal key (GTK) state at the particular supplicant; exchanging, by the particular supplicant, the GTK state with one or more neighbor supplicants in the computer network, wherein the exchanging comprises: receiving at least one beacon from at least one neighbor supplicant, each beacon comprising a GTK identifier (ID) for each GTK currently enabled on the neighbor supplicant; determining whether any inconsistencies exist in the GTK state at the particular supplicant based on the exchange; and in response to determining that any inconsistencies exist in the GTK state, performing, by the particular supplicant, 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.
