Abstract: A light-weight resilient mechanism is used to synchronize server secure keying data with member devices in a highly-scalable distributed group virtual private network (VPN). A server device generates an initial secure keying data set, for the VPN, that includes a first version identifier, and sends, to member devices and via point-to-point messages, the secure keying data set. The server device sends, to the member devices, heartbeat push messages including the first version identifier. The server device generates an updated secure keying data set with a second version identifier and sends, to the member devices, a key push message that includes the updated data set. The server device sends, to the member devices, heartbeat push messages including the second version identifier. Member devices may use the first and second version identifiers to confirm that secure keying data sets are current and quickly identify if updates are missed.
