That's on a different level of Dean;s 7-Layer Model -- the Political. The simplest approach is that a top-level authority (say, ITU) operate a top-level PKG that then provides private keys to the national authorities, who then act as PKGs for lower-level delegations, and on down to the individual phone number. So, if you're in possession of a private key for your phone number, from the PKG that's authoritative for your phone number (according to whichever definition of that authority we adopt), you are in possession of the identity indicated by that phone number. Not all that different from enum, just a different algorithm for the key management and crypto. -- Dean _______________________________________________ Sip mailing list http://www.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
