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 is 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 signed
with JSON Web Signature (JWS) and encrypted with JSON Web Encryption
(JWE) 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.
