3. Progress in May 2009 Meeting
Completed Proposal Presentation I
Work items #1 and #2 are covered by seven proposals (59,60,62,63,64,65,66)
Method-specific re-auth with standalone authenticator (EAP-FRM)
Security related events and commands
Security-related Information Elements
Packet-Level authentication
Use of hash trees for E2E IS protection
Proactive auth with media-independent authenticator architecture
MIH-level protection w/TLS handshake over MIH for key establishment
Pre-authentication root key with ERP over MIH and MIH_SEC_SAP
Relatively major specific issues
ERP vs. method-specific re-auth with standalone authenticator in terms of implementation easiness and required standardization work
Message authentication with short-term cert vs. message authentication with SA establishment
Trust model with MIH intermediary for e2e IS protection
Media-independent authenticator (MIA) architecture
MIH_SEC_SAP vs. MIHF w/integrated security module
Context binding details
