A Pseudo-Random Function for the Kerberos V Generic Security Service Application Program Interface Mechanism
RFC 7802, “A Pseudo-Random Function for the Kerberos V Generic Security Service Application Program Interface Mechanism”, is a Proposed Standard document published in March 2016 by S. Emery, N. Williams. It obsoletes RFC 4402. The canonical text is published by the RFC Editor.
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
