摘要： 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.

摘要： 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. 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.
摘要翻译：在一个实施例中，密钥分发处理从密钥服务器发送旨在被至少一个组成员设备接收的多播探测消息。密钥分发过程还在密钥服务器处接收到来自接收到多播探测消息的每个组成员设备的确认消息。依次，密钥分发处理从密钥服务器发送打算由密钥服务器从其收到确认消息的每个组成员设备接收的多播重新密钥数据消息。此外，密钥分发处理从密钥服务器向单个密钥服务器未接收到确认消息的每个组成员设备发送单播重新密钥数据消息。
