Abstract:
1. A method comprising: receiving by an agent a request from a network node for generation of a cryptographically generated IPv6 address for use by the network node, the request including a selected subset of parameters selected by the network node and required for generation of the cryptographically generated IPv6 address according to a prescribed cryptographic address generation procedure, the selected subset including at least a public key owned by the network node; dynamically generating by the agent at least a second of the parameters required for generation of the cryptographically generated IPv6 address, the second of the parameters including a random number dynamically generated by the agent; generating by the agent the cryptographically generated IPv6 address based on the selected subset and the second of the parameters required for generation of the cryptographically generated IPv6 address; and outputting, by the agent to the network node, an acknowledgment to the request and that includes the cryptographically generated IPv6 address, and the parameters required for generation of the cryptographically generated IPv6 address, wherein the network node retains exclusive authority for signing any neighbor advertisement message associated with the cryptographically generated IPv6 address, according to a prescribed secure neighbor discovery protocol.
