Here is what I propose for an IESG note to clarify IESG review comments "Suite B algorithms are defined to support two minimum levels of security: 128 and 192 bits. It is believed that the Suite B algorithms continue to meet these security goals. The algorithm identifiers for all of the Suite B algorithms remain available for anyone that wants to use them." |

Reclassification of Suite B Documents to Historic Status
Abstract
This document reclassifies the RFCs related to the United States
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: RFCs 5759, 6239,
6318, 6379, 6380, 6403, and 6460. In addition, it moves three
obsolete Informational RFCs to Historic status: RFCs 4869, 5008, and
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].

RFC 8423 Suite B to Historic July 2018
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:
o [RFC4869], "Suite B Cryptographic Suites for IPsec" (Obsoleted by
RFC 6379)
o [RFC5008], "Suite B in Secure/Multipurpose Internet Mail
Extensions (S/MIME)" (Obsoleted by RFC 6318)
o [RFC5430], "Suite B Profile for Transport Layer Security (TLS)"
(Obsoleted by RFC 6460)
