Numerous security mechanisms have been deployed on the Internet to manage access to various resources. These mechanisms have been generalized and scaled over the last decade through mechanisms such as the Simple Authentication and Security Layer (SASL) with the Generic Security Server Application Program Interface (GSS-API) (known as the GS2 family) [RFC5801]; the Security Assertion Markup Language (SAML) [OASIS.saml-core-2.0-os]; and the Authentication, Authorization, and Accounting (AAA) architecture as embodied in RADIUS [RFC2865] and Diameter [RFC6733].
