Mortimore, M. Jones, Y. Goland Status: Standards Track Stream: IETF Date: May 2015 Mailbox: brian.d.campbell@gmail.com, cmortimore@salesforce.com, mbj@microsoft.com, yarong@microsoft.com Pages: 20 Characters: 44458 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-oauth-assertions-18.txt URL: https://www.rfc-editor.org/info/rfc7521 DOI: http://dx.doi.org/10.17487/RFC7521 This specification provides a framework for the use of assertions with OAuth 2.0 in the form of a new client authentication mechanism and a new authorization grant type. Mechanisms are specified for transporting assertions during interactions with a token endpoint; general processing rules are also specified. The intent of this specification is to provide a common framework for OAuth 2.0 to interwork with other identity systems using assertions and to provide alternative client authentication mechanisms. Note that this specification only defines abstract message flows and processing rules. In order to be implementable, companion specifications are necessary to provide the corresponding concrete instantiations. This document is a product of the Web Authorization Protocol Working Group of the IETF. This is now a Proposed Standard.
