National Institute of Standards and Technology June 9, 2009 – Federal Register Recent Federal Regulation Documents

This notice announces the Secretary of Commerce's approval of Federal Information Processing Standard (FIPS) Publication 186-3, Digital Signature Standard (DSS). FIPS 186-3 is a revision of FIPS 186- 2. The FIPS specifies three techniques for the generation and verification of digital signatures that can be used for the protection of data: the Digital Signature Algorithm (DSA), the Elliptic Curve Digital Signature Algorithm (ECDSA) and the Rivest-Shamir-Adelman (RSA) algorithm. Although all three of these algorithms were approved in FIPS 186-2, FIPS 186-3 increases the key sizes allowed for DSA, provides additional requirements for the use of RSA and ECDSA, and includes requirements for obtaining the assurances necessary for valid digital signatures. FIPS 186-2 contained specifications for random number generators (RNGs); this revision does not include such specifications, but refers to NIST Special Publication (SP) 800-90 for obtaining random numbers. FIPS 186-3 is available at https://csrc.nist.gov/publications/ PubsFIPS.html; SP 800-90 is available at https://csrc.nist.gov/ publications/PubsSPs.html.
