Abstract

"Generic Security Service Application Program Interface Version 2, Update 1" [RFC2743] provides a generic interface for security services in the form of an abstraction layer over the underlying security mechanisms that an application may use. A GSS initiator and acceptor exchange messages, called "tokens", until a security context is established. Such a security context allows for each party to authenticate the other, the passing of confidential and/or integrity- protected messages between the initiator and acceptor, the generation of identical pseudorandom bit strings by both participants [RFC4401], and more.

     Structure of the Generic Security Service (GSS) Negotiation Loop

Abstract

   This document specifies the generic structure of the negotiation loop    to establish a Generic Security Service (GSS) security context    between initiator and acceptor.  The control flow of the loop is    indicated for both parties, including error conditions, and    indications are given for where application-specific behavior must be    specified.
