Recommendation for Pair-Wise Key Establishment Schemes Using Integer Factorization Cryptography: NIST SP 800-56B Rev. 2 | NIST

NIST has released an updated version of its SP 800-56B standard, which focuses on key-establishment schemes using integer factorization cryptography. The revision includes several key changes:

1. Approval of additional key sizes for key establishment
2. Removal of provisions for using the Triple Data Encryption Algorithm (TDEA)
3. Removal of the KTS-KEM-KWS key-transport scheme from previous versions

The key derivation methods previously included in SP 800-56B have been moved to the updated SP 800-56C standard. This revision aims to provide more flexibility and security for key establishment in systems with a growing number of entities, while removing outdated or less secure methods.

The updated standards are important for U.S. government systems that rely on strong cryptographic schemes to protect sensitive data. Implementing these standards will help ensure the security and integrity of government information technology systems as they evolve and scale.
