Cryptography is tantamount to cyber-securing an information technology 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. The loss or manipulation of such data could affect a business’s profitability, reveal personally identifiable information, or in some extreme cases, jeopardize national security.
Cryptography relies on two basic components: an algorithm (or cryptographic methodology) and a cryptographic key. Special Publication Revision 2 discusses the generation of the keys to be managed and used by the approved cryptographic algorithms, NIST said in a release.
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.
