Lots and lots of L2 specific Authority to Citizen alert technology Most of it is aimed at least common denominator devices Very often, very limited definition of “Authority” ◦ Most are single authority, and to cope, each authority has its own system Virtually all have no opt-out, very few have any form of opt-in
IETF emergency efforts started with Authority to Authority 9 years ago Citizen to Authority work started 7 years ago We’ve been talking about Authority to Citizen for at least 4 years, maybe longer
“Authority TO Citizen Alerts” = atoca BOF held, charter discussions have been held for over a year post BOF We now have an agreed upon charter, but need IESG approval to create a work group
Any IP connected endpoint Not L2 specific, hopefully able to use L2 available L2 mechanisms Complementary to other L2 specific mechanisms (CMAS, EWS, …) – people will have lots of devices Initial target is a limited set of Authorities (government) atoca won’t discuss how they are appointed, but will describe the authentication and authorization MECHANISMS
Explicit opt-in and opt-out mechanisms ◦ Governments may proscribe controls on this for some kinds of messages Initial design is small messages that can be rendered in a variety of ways by devices ◦ May contains links to further information Location based delivery, but not necessarily the location of the device Use available tools, e.g. CAP Security is a big deal to be faced
