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.
