Title : Channel Binding Signalling for the Generic Security
Services Application Programming Interface

Abstract:
Channel binding is a technique that allows applications to use a
secure channel at a lower layer without having to use authentication
at that lower layer. The concept of channel binding comes from the
Generic Security Services Application Programming Interface (GSS-
API). It turns out that the semantics commonly implemented are
different that those specified in the base GSS-API RFC (RFC2743), and
that that specification has a serious bug. This document addresses
both, the inconsistency as-implemented and the specification bug.
This Internet-Draft proposes the addition of a "channel bound" return
flag for the GSS_Init_sec_context() and GSS_Accept_sec_context()
functions. Two behaviors are specified: a default, safe behavior
reflecting existing implementation deployments, and a behavior that
is only safe when the application specifically tells the GSS-API that
it (the application) supports the new behavior. Additional API
elements related to this are also added, including a new security
context establishment API.
