RE: [LinkSec] LinkSec Security Issues & 802.10

Ken,
 
1. All the participants in the LinkSec effort are aware about the urgency of providing a solution of the EPON problems. While there seems to be some convergence on the need to bring amendments and extensions to SDE, it is not clear that this solves all the problems of security in EPON.
2. There is a practical aspect in avoiding effort duplication. With LinkSec chartered and runing, it will be difficult for many participants to attend both LinkSec and a re-newed 802.10. After all, you guys (802.10 participants) had a hard time sending representatives to the first few LinkSec SG meetings, though nobody probably questions your interest in IEEE 802 security.
 
I suggest that for the time being we focus our efforts in the framework offered by the LinkSec work, and decide - maybe not later than at the July plenary - where will this reside. For example, you can present the proposals for SDE extensions as a contribution to the LinkSec interim meeting in Ottawa.
 
Thanks,
 
Dan

Dan-

I agree that we do not want two conflicting efforts going on at the same time.  However, my view is that the LinkSec SG is very much in favor of using SDE as the frame protection protocol.  To that end, I proposed revisions to SDE in support of perceived LinkSec requirements.  I said:

 "The modifications are needed in order to accommodate replay protection, destination MAC address authentication, and optional integrity protection of additional header fields, such as the VLAN tag."

I do not think it is prudent to delay this work.  I feel an urgency in the 802.3 EPON community to provide a security solution as quickly as possible.  So, if you agree that the consensus is to use SDE, then why not get the SDE revision work started tomorrow?
