Abstract
Techniques for distributing a new communication key within a group virtual private network (VPN) are provided. A key distribution service determines that a new communication key for a VPN is to be distributed to members of the VPN. The new communication key is sent individually in a unique and separate message to each of the members. The key distribution service also maintains records to determine which of the members have and have not successfully received the new communication key.
