Abstract

Protocols and architecture for secure virtual private networks.
Intraenterprise data communications are supported in a secure manner over the Internet or other public network space with the implementation of secure virtual private networks. Members of a virtual private network group exchange data that may be compressed, encrypted and authenticated, if the exchange is between members of the group.
