You have msec on the list of recipients, which is where I (not an active participant, mind you) think the answer lies. Both GDOI (RFC 3547) and GSAKMP (RFC 4535) are group key management protocols, which is what OSPFv3 needs. Unfortunately, both assume the existence of a group controller that plays an important role in distributing keys. In other words, the very democratic all-are-equal many-to-many model of OSPF might find it difficult to map to the envisioned group security architecture. I suppose it might be possible to consider the Designated Router as the group controller, but as the DR is elected, that might be a difficult fit. Even if you solve the group key management problem for OSPFv3, you still have the difficulty to doing anti-replay in a multicast environment. Manral presented a draft some years ago to the rpsec working group about the crypto vulnerabilities of routing protocols, and concentrated for OSPFv3 on replay vulnerabilities. Unfortunately, that did not go anywhere. Just for fun, I'm adding the routing area ADs and the secdir on this list. This is one of those cross-disciplinary concerns that has the right people in several different wgs and areas. The more the merrier, right? The one quibble I have is that the tsvwg probably has little to do with this problem - the transport for OSPFv3 is IP, not TCP, and IP is not the level of stuff their charter looks at. (And sorry for the late reply to your messages, I've been mulling the options.) --Sandy --------- In reply to ------------------------ Date: Tue, 23 Sep 2008 17:52:07 -0400 From: Ed Jankiewicz <[EMAIL PROTECTED]> To: [EMAIL PROTECTED], [EMAIL PROTECTED], [email protected], [EMAIL PROTECTED], [EMAIL PROTECTED] Subject: [RPSEC] Authentication for OSPFv3 I am not an active follower of these lists but have a question. Please reply off-list directly to [EMAIL PROTECTED] or copy me if this triggers relevant discussion on your list. What (if any) current initiatives are there that would support automated key exchange for OSFPv3 authentication? RFC 4552 relies upon pre-shared secret keys for generating message digest, but some of my constituents have issues with manual generation, distribution and configuration of keys in their IPv6 network deployment. Is any of the current work on IKE revisions applicable, any work being done in your working group, or do you know of any OSPF-specific solution being developed somewhere?
