The National Institute of Standards and Technology announces the publication of NIST Special Publication (SP) 800-133 Revision 2, Recommendation for Cryptographic Key Generation, which discusses the generation of the keys to be managed and used by the approved cryptographic algorithms. This revision provides a method for determining a symmetric key by combining multiple keys and other data, NIST reported in a release.
Cryptography is typically used in an information technology secure environment to protect data that is sensitive, has a high value, or is vulnerable to unauthorized disclosure or undetected modification during transmission or while in storage. Cryptography relies on two basic components: an algorithm (or cryptographic methodology) and a cryptographic key. NIST’s recommendation discusses the generation of the keys to be managed and used by the approved cryptographic algorithms.
