The IESG has received a request from the Web Authorization Protocol WG (oauth) to consider the following document: - 'The OAuth 2.0 Authorization Framework: JWT Secured Authorization Request (JAR)' <draft-ietf-oauth-jwsreq-11.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-02-13. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The authorization request in OAuth 2.0 described in RFC 6749 utilizes query parameter serialization, which means that Authorization Request parameters are encoded in the URI of the request and sent through user agents such as web browsers. While it is easy to implement, it means that (a) the communication through the user agents are not integrity protected and thus the parameters can be tainted, and (b) the source of the communication is not authenticated. Because of these weaknesses, several attacks to the protocol have now been put forward. This document introduces the ability to send request parameters in a JSON Web Token (JWT) instead, which allows the request to be JWS signed and/or JWE encrypted so that the integrity, source authentication and confidentiality property of the Authorization Request is attained. The request can be sent by value or by reference. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-oauth-jwsreq/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-oauth-jwsreq/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: rfc6234: US Secure Hash Algorithms (SHA and SHA-based HMAC and HKDF) (Informational - IETF stream) rfc6819: OAuth 2.0 Threat Model and Security Considerations (Informational - IETF stream) rfc6973: Privacy Considerations for Internet Protocols (Informational - IAB stream) Note that some of these references may already be listed in the acceptable Downref Registry.
