RFC 5430 Suite B for TLS March 2009
Abstract
The United States government has published guidelines for "NSA Suite
B Cryptography", which defines cryptographic algorithm policy for
national security applications. This document defines a profile of
Transport Layer Security (TLS) version 1.2 that is fully conformant
with Suite B. This document also defines a transitional profile for
use with TLS version 1.0 and TLS version 1.1 which employs Suite B
algorithms to the greatest extent possible.

1. Introduction
The United States government has posted the Fact Sheet on National
Security Agency (NSA) Suite B Cryptography [NSA], and at the time of
writing, it states:
To complement the existing policy for the use of the Advanced
Encryption Standard (AES) to protect national security systems
and information as specified in The National Policy on the use of
the Advanced Encryption Standard (AES) to Protect National
Security Systems and National Security Information (CNSSP-15),
the National Security Agency (NSA) announced Suite B Cryptography
at the 2005 RSA Conference. In addition to the AES, Suite B
includes cryptographic algorithms for hashing, digital
signatures, and key exchange.
Suite B only specifies the cryptographic algorithms to be
used. Many other factors need to be addressed in determining
whether a particular device implementing a particular set of
