Abstract

   This document presents use cases for authentication and access
   control in scenarios involving constrained RESTful devices.  Where
   specific details are relevant, it is assumed that the devices use
   CoAP as communication protocol, however most conclusions apply
   generally.

   A number of security requirements are derived from the use cases,
   which are intended as a guideline for developing a comprehensive
   authentication and access control approach for this class of
   scenarios.
