• Progress• Completed Proposal Presentation II with detailed text• Identified Major Overlaps in Work Item #2

• In-band authentication and SA establishment (DCN 102)• Out-of-band authentication and SA establishment (DCN 105) • Packet level authentication w/o SA establishment (DCN 107)

• Issues (to be discussed in Teleconferences)• DCN 102 needs to clarify if L2 specification needs to be changed• DCN 102 may need to specify a key distribution mechanism from MIA-KH and

MSA-KH• MIH security primitives for passing MIH messages over MIH_SAP do not fit 802.21

primitive usage (DCN 105)• Primary / Secondary PoS concept needs detailed trust model and consideration for

Domino effect (DCN 105)• Generating Candidate_PoA_Detected event may be unnecessary or difficult to

support (DCN 103)• Packet Level Authentication needs to be defined in IETF first (DCN 107)

• Next Steps• Detailed text is needed• Only revised proposals are accepted• Submission deadline for proposals: September 13th, 2009 end of day AOE
