NSA Suite B Cryptography (Suite B) is a National Security Agency (NSA) recommended a set of interoperable cryptographic algorithms.

NSA Suite B Cryptography standard specifies a mode of operation in which only a specific set of secure cryptographic algorithms are used.

NSA Suite B Cryptography:

Additionally, the IETF RFC 6460 standard specifies NSA Suite B Cryptography compliant profiles which define the detailed application configuration and behavior necessary to comply with the NSA Suite B Cryptography standard. RFC 6460 defines two profiles:

  • NSA Suite B Cryptography compliant profile for use with TLS 1.2. When configured for Suite B compliant operation, only the restricted set of cryptographic algorithms listed above will be used.
  • A transitional profile for use with TLS 1.0 or TLS 1.1. This profile enables interoperability with non-NSA Suite B Cryptography compliant servers. When configured for NSA Suite B Cryptography transitional operation, additional encryption and hashing algorithms
may be used.

NSA Suite B Cryptography standard is conceptually similar to FIPS 140-2, because it restricts the set of enabled cryptographic algorithms in order to provide an Level Of Assurance.
