  5. Some Sobering Facts… • No AAA protocol document specifying key distribution has ever been approved as an IETF Proposed Standard • RFC 2548 is Informational (and vendor-specific) • Diameter MIPv4 is blocked on security • No progress on Diameter EAP or CMS • What does AAA WG need to do in order to make progress? • What aspects of the problem have we missed? • What criteria do we need to meet? AAA WG, IETF 56

  6. Where Do We Go From Here? • Need a fresh start on Diameter Mobile IPv4 • WG: Address IESG concerns on clarity of system description • IESG: Provide more detailed feedback on how draft needs to be changed to conform the principles • Need a key framework document • Describe the protocols and how they interact system (EAP, AAA, TSK derivation) • Analyze the security properties of the system • Enumerate the security requirements • Address key naming and binding issues (including examples) • EAP WG: draft-aboba-pppext-key-problem-06.txt • Split out Diameter Key Wrap into a separate document • Create a design team to focus on this. • Take a fresh look at Diameter CMS • Can we remove deployment barriers? • Can we decrease the complexity of the specification? • Any implementation plans? AAA WG, IETF 56
