Abstract
A node that couples to the Internet establishes a secure connection with another node that couples to the Internet. The secure connection to be established via an IPsec security association. The node registers with an authority that couples to the Internet and provides public key infrastructure (PKI) services. Registration is to include obtaining both a private and a public and key. The PKI services to include providing the private key to only the registered node and providing the public key to another registered node that requests PKI services from the authority. The node requests the PKI services from the authority based on a change in a point of attachment for the node to the Internet. The node then authenticates the other node via the PKI services and exchanges a secret key with the other node based on the authentication of the other node. The node is to implement an encryption scheme that uses the exchanged secret key for symmetric encryption of data exchanged between the node and the other node. The symmetric encryption is to maintain a secure connection between the nodes.
