Method and apparatus for providing a virtual private network
First Claim
1. A method for establishing a virtual private network including a master node, and slave nodes, the method comprising:
- establishing a plurality of nodes by a public network, and each of the nodes including a public key and a private key in a first cryptographic mode;
providing in the master node configuration information that defines allowable virtual private network communication links between each of the nodes;
securely and electronically transferring the configuration information to each of the slave nodes from the master node; and
establishing the virtual private network links among each of the nodes based upon the configuration information.

Abstract
A method and apparatus for establishing a virtual private network provides a technique for automatically configuring nodes of the network. The nodes are established to include a master node. Each node includes a public key and a private key for cryptographic communication in a first mode, such as RSA. Configuration data regarding communication in the network is provided to the master node. The configuration data is securely transferred into each other node from the master node. Nodes communicate with each other based upon a configuration data. The configuration data can include cryptographic key data related to a second cryptographic mode such as Diffie-Hellman.
