Request by JWS ver.1.0 for OAuth 2.0
draft-ietf-oauth-jwsreq-04
Abstract
The authorization request in OAuth 2.0 utilizes query parameter
serialization. This specification defines the authorization request
using JWT serialization. The request is sent through "request"
parameter or by reference through "request_uri" parameter that points
to the JWT, allowing the request to be optionally signed and
encrypted.

1. Introduction
The parameters "request" and "request_uri" are introduced as
additional authorization request parameters for the OAuth 2.0
[RFC6749] flows. The "request" parameter is a JSON Web Token (JWT)
[RFC7519] whose JWT Claims Set holds the JSON encoded OAuth 2.0
authorization request parameters. The [RFC7519] can be passed to the
authorization endpoint by reference, in which case the parameter
"request_uri" is used instead of the "request".
Using [RFC7519] as the request encoding instead of query parameters
has several advantages:
1. The request may be signed so that integrity check may be
implemented. If a suitable algorithm is used for the signing,
then non-repudiation property may be obtained in addition.
2. The request may be encrypted so that end-to-end confidentiality
may be obtained even if in the case TLS connection is terminated
at a gateway or a similar device.
There are a few cases that request by reference are useful such as:

1. When it is detected that the User Agent does not support long
URLs: Some extensions may extend the URL. For example, the
client might want to send a public key with the request.
