OSCORE profile of the Authentication and Authorization for Constrained
Environments Framework
draft-ietf-ace-oscore-profile-06
Abstract
This memo specifies a profile for the Authentication and
Authorization for Constrained Environments (ACE) framework. It
utilizes Object Security for Constrained RESTful Environments
(OSCORE) to provide communication security, server authentication,
and proof-of-possession for a key owned by the client and bound to an
OAuth 2.0 access token.
