Web Authorization Protocol (oauth) ---------------------------------- Charter Last Modified: 2011-06-14 Current Status: Active Working Group Chair(s): Blaine Cook <romeda@gmail.com> Hannes Tschofenig <Hannes.Tschofenig@gmx.net> Barry Leiba <barryleiba@computer.org> Security Area Director(s): Stephen Farrell <stephen.farrell@cs.tcd.ie> Sean Turner <turners@ieca.com> Security Area Advisor: Stephen Farrell <stephen.farrell@cs.tcd.ie> Technical Advisor(s): Peter Saint-Andre <stpeter@stpeter.im> Mailing Lists: General Discussion:oauth@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/oauth Archive: http://www.ietf.org/mail-archive/web/oauth/current/maillist.html Description of Working Group: The Web Authorization (OAuth) protocol allows a user to grant a third-party Web site or application access to the user's protected resources, without necessarily revealing their long-term credentials, or even their identity. For example, a photo-sharing site that supports OAuth could allow its users to use a third-party printing Web site to print their private pictures, without allowing the printing site to gain full control of the user's account. OAuth encompasses * a mechanism for a user to authorize issuance of credentials that a third party can use to access resources on the user's behalf and * a mechanism for using the issued credentials to authenticate HTTP requests. In April 2010 the OAuth 1.0 specification, documenting pre-IETF work, was published as an informational document (RFC 5849). The working group has since been developing OAuth 2.0, a standards-track version that will reflect IETF consensus. Version 2.0 will consider the implementation experience with version 1.0, a discovered security vulnerability (session fixation attack), the use cases and functionality proposed with OAuth WRAP [draft-hardt-oauth-01] and will * improve the terminology used, * consider broader use cases, * embody good security practices, * improve interoperability, and * provide guidelines for extensibility. The working group will develop authentication schemes for peers/servers taking part in OAuth (accessing protected resources). This includes * an HMAC-based authentication mechanism This document aims to provide a general purpose MAC authentication scheme that can be used both with OAuth 2.0 but also with other use cases. The WG will work with the security and applications area directors to ensure that this work gets appropriate review, e.g. via additional last calls in other relevant working groups such as HTTPBIS, * a specification for access protected by Transport Layer Security (bearer tokens), * an extension to OAuth 2.0 to allow access tokens to be requested when a client is in possession of a SAML assertion. A separate informational description will be produced to provide additional security analysis for audiences beyond the community of protocol implementers. Milestones will be added for the later items after the near-term work has been completed.
