Abstract

Techniques are presented herein for optimizing secure communications in a network. A router in a virtual private network determines whether or not it has successfully registered with a key server that provides cryptographic keys for routers in the virtual private network. The router stores state information that is indicative of whether or not the router has successfully registered with the key server.
