Cryptography is often used in information technology security environments to protect sensitive, high-value data that might be compromised during transmission or while in storage. It relies upon two basic components: an algorithm (i.e., cryptographic methodology) and a cryptographic key. NIST has developed a wide variety of Federal Information Processing Standards (FIPS) and guidance to specify, approve, and manage cryptographic algorithms and keys for Federal Government use.

NIST invites comments on Draft Special Publication (SP) 800-133 Revision 1, Recommendation for Cryptographic Key Generation, which discusses the generation of keys to be managed and used by approved cryptographic algorithms. This revision adds the Edwards-curve Digital Signature Algorithm (EdDSA) to the original list of digital signature algorithms as well as KMAC as an algorithm for generating a Message Authentication Code (MAC). EdDSA will also be proposed as an additional signature algorithm in a forthcoming revision of Federal Information Processing Standard (FIPS) 186, Digital Signature Standard (DSS). KMAC is specified in SP 800-185, Recommendation for Discrete Logarithm-based Cryptography: Elliptic Curve Domain Parameters. Additional changes are listed in the final appendix of SP 800-133 Rev. 1.

A public comment period for this document is open until May 8, 2019.
