Patent abstract
A host requests a public key certificate from a gateway, and the gateway requests a public key certificate from a Certification Authority (CA). The CA generates a public key certificate, which is sent to the host through the gateway. The host sets an IPv6 address based on information from the gateway. The host requests and receives a new public key certificate whenever necessary, and sends a public key certificate including the IPv6 address to the communication counterpart.
