    A Pseudo-Random Function (PRF) for the Kerberos V Generic Security        Service Application Program Interface (GSS-API) Mechanism

Abstract

   This document defines the Pseudo-Random Function (PRF) for the    Kerberos V mechanism for the Generic Security Service Application    Program Interface (GSS-API), based on the PRF defined for the    Kerberos V cryptographic framework, for keying application protocols    given an established Kerberos V GSS-API security context.

   This document obsoletes RFC 4402 and reclassifies that document as    Historic.  RFC 4402 starts the PRF+ counter at 1; however, a number    of implementations start the counter at 0.  As a result, the original    specification would not be interoperable with existing    implementations.
