Authentication and Authorization for Constrained Environments (ACE)
draft-ietf-ace-oauth-authz-06
Abstract
This specification defines a framework for authentication and
authorization in Internet of Things (IoT) environments. The
framework is based on a set of building blocks including OAuth 2.0
and CoAP, thus making a well-known and widely used authorization
solution suitable for IoT devices. Existing specifications are used
where possible, but where the constraints of IoT devices require it,
extensions are added and profiles are defined.
