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
Background
![Page 3: Brian Rosen Neustar. Lots and lots of L2 specific Authority to Citizen alert technology Most of it is aimed at least common denominator devices](https://reader036.vdocuments.us/reader036/viewer/2022082918/551b9330550346a6148b60bc/html5/thumbnails/3.jpg)
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
