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. This document was reviewed by Russ Housley for the IESG.
