Abstract Abstract
This document describes OAuth client authentication and certificate This document describes OAuth client authentication and certificate
bound access tokens using mutual Transport Layer Security (TLS) bound access tokens using mutual Transport Layer Security (TLS)
authentication with X.509 certificates. OAuth clients are provided a authentication with X.509 certificates. OAuth clients are provided a
mechanism for authentication to the authorization sever using mutual mechanism for authentication to the authorization sever using mutual
TLS, based on either self-signed certificates or public key TLS, based on either self-signed certificates or public key
infrastructure (PKI). OAuth authorization servers are provided a infrastructure (PKI). OAuth authorization servers are provided a
mechanism for binding access tokens to a client's mutual TLS mechanism for binding access tokens to a client's mutual TLS
