Well, if I remember correctly, there was ample discussion of this topic during the IETF meeting in Paris -- both Steve Bellovin and I presented the issues with such techniques. Basic challenge response mechanisms like CRAM-MD5 are simply too weak to be used on the Internet. They are subject to dictionary attacks, which can retrieve the password in a very short time. They don't deserve much more than documentation for historical purpose. -- Christian Huitema _______________________________________________ Ietf mailing list [email protected] https://www1.ietf.org/mailman/listinfo/ietf
