MSEC meeting summary We spent 1 hour on Wednesday discussing new work items. There are requirements related to a signaling protocol (RSVP) and routing protocols (e.g., OSPF, NLS) which point to the need for group key management protocols. There are indications that the work needs to happen in MSEC; although there is caution from the TSV ADs that the requirements do not imply that a particular protocol can be adopted as a MSEC work item. The direction would have been to extend GDOI to satisfy these requirements. As it stands now, we see no urgency for that work to happen. It appears that may be a longer term goal and so we agreed to proceed with the current GDOI extensions work (unrelated to the new requirements, and related to hash algorithm agility and other minor changes based on implementation experience). The authors are advised to continue the work as individual work. Next, Dan Wing presented his SRTP key transport work which works over DTLS. MSEC has a work item on group keying for SRTP, GDOI-SRTP. Sheela Rowles compared to the two approaches and after some discussion the conclusion was to pursue optimization of GDOI-SRTP for large groups and DTLS-SRTP-Key transport for small groups. As a side note, Dan was asked to study if there are indeed difficulties in using the TLS-based solution for large groups. TESLA-for-alc-norm is ready for WGLC. There was also a presentation on extending MIKEY to support mode negotiation.
