Technical Summary
 
   This document describes a method for binding a public signature key
   to an IPv6 address in the Secure Neighbor Discovery (SEND) protocol.
   Cryptographically Generated Addresses (CGA) are IPv6 addresses where
   the interface identifier is generated by computing a cryptographic
   one-way hash function from a public key and auxiliary parameters. The
   binding between the public key and the address can be verified by
   re-computing the hash value and by comparing the hash with the
   interface identifier. Messages sent from an IPv6 address can be
   protected by attaching the public key and auxiliary parameters and by
   signing the message with the corresponding private key. The
   protection works without a certification authority or other security
   infrastructure.
