Reports on Information Technology

The Information Technology Laboratory (ITL) at the National Institute of Standards and Technology

(NIST) stimulates U.S. economic growth and industrial competitiveness through technical leadership

and collaborative research in critical infrastructure technology, including tests, test methods, reference

data, and forward-looking standards, to advance the development and productive use of information

technology. To overcome barriers to usability, scalability, interoperability, and security in information

systems and networks, ITL programs focus on a broad range of networking, security, and advanced information

technologies, as well as the mathematical, statistical, and computational sciences. This Special

Publication 500-series reports on ITL’s research in tests and test methods for information technology,

and its collaborative activities with industry, government, and academic organizations.
