This document defines a Key-Derivation Authentication Scheme, based on the PBKDF2 Key Derivation Function (KDF), that could be used with the challenge-response authentication framework used by SIP to authenticate the user. The scheme allows two parties to establish a mutually authenticated communication channel based on a shared password, without ever sending the password on the wire.
