Abstract
A key selection process is provided which secures traffic between VPN end-points using a combination of SVPN group keys and pair-wise keys. The type of key used is based on the dynamic needs of traffic between the end-points, where the needs may include throughput and quality of service. SVPN group keys allow end-points in a group to initiate data communications while obtaining pair-wise keys in the background. Once pair wise keys are obtained, communications can be transferred using the obtained keys. As the throughput, quality of service, routing and other needs of the channel change, the type of keys used for data transfer may concomitantly change between SVPN group keys and pair-wise keys to appropriately utilize network resources. The key selection idea may be extended to allow communication through a hub using a group key while establishing pair-wise channels for group member communications in the background.
