        Reclassification of Suite B Documents to Historic Status
                  draft-housley-suite-b-to-historic-04

Abstract

   This document reclassifies the RFCs related to the U.S.  National
   Security Agency (NSA) Suite B cryptographic algorithms as Historic,
   and it discusses the reasons for doing so.  This document moves seven
   informational RFCs to Historic Status: RFC 5759, RFC 6239, RFC 6318,
   RFC 6379, RFC 6380, RFC 6403, and RFC 6460.  In addition, this
   document moves three obsolete informational RFCs to Historic Status:
   RFC 4869, RFC 5008, and RFC 5430.

1.  Introduction

   Several RFCs profile security protocols for use with the National
   Security Agency (NSA) Suite B Cryptography.  Suite B is no longer
   supported by NSA, and the web pages that specify the cryptographic
   algorithms are no longer available.

   In July 2015, NSA published the Committee for National Security
   Systems Advisory Memorandum 02-15 as the first step in replacing
   Suite B with NSA's Commercial National Security Algorithm (CNSA)
   Suite.  Information about the CNSA Suite can be found in [CNSA].

2.  Rationale

   As indicated in [CNSA], NSA is transitioning from Suite B to the CNSA
   Suite.  As a result, the profiles of the security protocols for the
   Suite B algorithms are now only of historic interest.

3.  The RFCs Related to Suite B

   Between 2007 and 2012, several Suite-B-related RFCs were published to
   profile security protocols for use with the Suite B algorithms.  They
   are:
