Suite B Profile for Transport Layer Security (TLS)
Abstract
The United States government has published guidelines for "NSA Suite
B Cryptography" that define cryptographic algorithm policy for
national security applications. This document defines a profile of
Transport Layer Security (TLS) version 1.2 that is fully compliant
with Suite B.

1. Introduction
This document specifies the conventions for using National Security
Agency (NSA) Suite B Cryptography [SuiteB] with the Transport Layer
Security (TLS) protocol, and the Datagram Transport Layer Security
(DTLS) protocol.
This document does not define any new cipher suites; instead, it
defines a Suite B compliant profile for use with TLS version 1.2
[RFC5246], DTLS version 1.2 [RFC6347], and the cipher suites defined
