The rekey distribution process also receives, at the key server, an acknowledgement message from each group member device that received the multicast probe message. In turn, the rekey distribution process transmits, from the key server, a multicast rekey data message intended to be received by each group member device from which the key server received an acknowledgment message. Furthermore, the rekey distribution process transmits, from the key server, a unicast rekey data message to each group member device from which the key server did not receive an acknowledgment message."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hybrid rekey distribution in a virtual private network environment","description":"In one embodiment, a rekey distribution process transmits, from a key server, a multicast probe message intended to be received by at least one group member device.
