An Authorization Information Format (AIF) for ACE
draft-ietf-ace-aif-00
Abstract
Constrained Devices as they are used in the "Internet of Things" need
security. One important element of this security is that devices in
the Internet of Things need to be able to decide which operations
requested of them should be considered authorized, need to ascertain
that the authorization to request the operation does apply to the
actual requester, and need to ascertain that other devices they place
requests on are the ones they intended.
To transfer detailed authorization information from an authorization
manager (such as an ACE-OAuth Authorization Server) to a device, a
representation format is needed. This document provides a suggestion
for such a format, the Authorization Information Format (AIF). AIF
is defined both as a general structure that can be used for many
different applications and as a specific refinement that describes
REST resources and the permissions on them.
