In the old days, when Project 802 was sponsored by the IEEE technical
Committee on Computer Communications (TCCC), the whole activity was
to layers 1 and 2. When 802.10 was formed, there was a strong belief
key management would require work outside of layers 1 and 2, and for
reason 802.10 had two sponsors TCCC and the Technical Committee on
and Privacy (TCSP). As a result, key management standards at layer 7
included in the 802.10 PARs, and in fact 802.10c is an application layer
In my opinion, key management cannot be solved in layer 1 and 2.
architecture support this view, including the security work in 802.11
In order to solve the key management, 802.1 would need to partner with
another activity, probably the IETF.

802.10 needs to come out of hibernation this year anyway. SDE (802.10b)
due for a five year review. Since this LAN/MAN security protocol meets
most of the LinkSec security encapsulation requirements, it is
to make modifications to SDE to meet the remainder of the requirements.

You are correct that 802.1X is being used by a larger number of
vendors. And, the current work in 802.11 will lead to further
I know several people, including myself, who did not attend the LinkSec
meeting because of the scheduling. I am sure that there was no date
would accommodate everyone's schedule.

The necessary activity is the same in all cases -- write a PAR and get

would need to build voting rights. On the other hand, bringing a group
of hibernation seems very similar to starting a new group. So, it is my
assertion that everyone at the initial meeting would be granted voting
