    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.},
