This National Institutes of Standards and Technology Federal Information Processing Standards Publication 180-4 "Secure Hash Standard (SHS)" specifies secure hash algorithms, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224 and SHA-512/256. All of the algorithms are iterative, one-way hash functions that can process a message to produce a condensed representation called a message digest. These algorithms enable the determination of a message's integrity: any change to the message will, with a very high probability, result in a different message digest. This property is useful in the...

With the continuing frequency, intensity, and adverse consequences of cyber-attacks, disruptions, hazards, and other threats to federal, state, and local governments, the military, businesses, and the critical infrastructure, the need for trustworthy secure systems has never been more important to the long-term economic and national security interests of the United States. Engineering-based solutions are essential to managing the growing complexity, dynamicity, and interconnectedness of today's systems, as exemplified by cyber-physical systems and systems-of-systems, including the Internet of...

NIST Handbook 44 was first published in 1949, having been preceded by similar handbooks of various designations and in several forms, beginning in 1918. NIST Handbook 44 is published in its entirety each year following the Annual Meeting of the National Conference on Weights and Measures (NCWM). The Committee on Specifications and Tolerances of the NCWM developed the 2017 edition with the assistance of the Office of Weights and Measures (OWM) of the National Institute of Standards and Technology (NIST). This handbook includes amendments endorsed by the 101da National Conference on Weights and...
