2.  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

3.  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

4.  “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

5.  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

6.  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
