Use Cases for Authentication and Authorization
in Constrained Environments
Abstract
Constrained devices are nodes with limited processing power, storage
space, and transmission capacities. In many cases, these devices do
not provide user interfaces, and they are often intended to interact
without human intervention.
This document includes a collection of representative use cases for
authentication and authorization in constrained environments. These
use cases aim at identifying authorization problems that arise during
the life cycle of a constrained device and are intended to provide a
guideline for developing a comprehensive authentication and
authorization solution for this class of scenarios.
Where specific details are relevant, it is assumed that the devices
use the Constrained Application Protocol (CoAP) as a communication
protocol. However, most conclusions apply generally.
