Internet Engineering Task Force (IETF) M. Salter Request for Comments: 6460 National Security Agency Obsoletes: 5430 R. Housley Category: Informational Vigil Security ISSN: 2070-1721 January 2012 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.

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 in [RFC5289]. This profile uses only Suite B algorithms. Salter & Housley Informational [Page 2]Show full document text
