1.4 Relationship to Other Protocols

The OpenID Connect 1.0 Protocol Extensions (this document) specify extensions to the industry standard OpenID Connect 1.0 Protocol that is defined in [OIDCCore] and [OIDCDiscovery]. These extensions are dependent on the OpenID Connect 1.0 protocol and the OAuth 2.0 protocol [RFC6749] and OAuth 2.0 Protocol Extensions [MS-OAPX], and use HTTPS [RFC2818] as the underlying transport protocol.
