Technical Summary

  This document analyzes the implications of recent attacks on commonly
  used one-way hash functions on Cryptographically Generated Addresses
  (CGAs) and updates RFC 3972 to support multiple hash algorithms.  An
  IANA registry is established to register hash functions for CGAs.

Working Group Summary

  This document is not the result of any IETF Working Group.

Protocol Quality

  The protocol is designed to "future-proof" CGAs against attacks that
  have not yet occurred.
