I think this is a good and timely thing for the IETF to do. One part of this where I think it might be useful to get some broader input (which may have happened already, I'm not sure) is the following: On 19/04/11 17:56, IESG Secretary wrote: > The protocol must protect both the channel enablement process and the > privacy of users. That part is fine but it goes on to say: > Robust security mechanisms are required to prevent: > device identity spoofing, modification of device requests, modification > of channel enablement information, ... I'm told (and believe) this in response to (at least) US FCC requirements that call for a device ID and sometimes serial number to be (securely, for some value of securely) sent with the query. Those appear to be real regulatory requirements in the US, presumably so the regulator can stomp on someone who messes about in the wrong spectrum at the wrong time. (The link below [1] may be to the right or wrong bit of those US regulations, I'm not at all sure, not being from there;-) So my questions: Are there may be similar (or conflicting!) requirements elsewhere? Does this bit of the charter text need changes to work well for other regions? Separately, I'm not sure how to square those kinds of regulatory requirements with protecting privacy where the device is carried by a person and has some FCC device ID (which lots do I guess) and the person might not want the database operator to know who's asking. But I think that's ok as something for the WG to figure out since the charter already calls for respecting privacy. I'm more concerned in case e.g. some other regional regulation called for this protocol to be completely anonymous or something, in which case the current charter text might be problematic. Cheers, Stephen.
