Cryptography uses mathematical techniques to protect the security of information. The NIST Cryptographic Technology Group develops and advances the cryptographic standards, guidelines, and algorithms that protect the nation’s digital information. Guided by its mission and by federal statutes and policy directives, the group works to strengthen the security technologies that enable innovation, support economic growth, and safeguard national security. For more than 50 years, NIST has worked with industry, government, and academia through open, collaborative processes to develop cryptographic standards, guidelines, and technologies to secure sensitive information and information systems.
Our work in cryptography has continually evolved to meet the needs of the changing information technology landscape. Today, NIST cryptographic standards and guidelines are used in applications from tablets and cellphones to ATMs, to secure global electronic commerce, to protect U.S. federal information, and secure personal information.
NIST makes sure the U.S. has the right cryptographic tools ready as new technologies move from research into operation. For example, NIST is developing post-quantum cryptography to protect our data when quantum computing becomes a reality. At the other end of the spectrum, we are advancing lightweight cryptography to accommodate the security needs of the ever-growing uses of technology in our everyday lives.
The Cryptographic Technology Group coordinates with other cybersecurity programs at NIST to support the adoption and use of secure cryptographic technologies. These include the Cryptographic Module Validation Program, which validates implementations cryptography in products, and the National Cybersecurity Center of Excellence, which helps to bridge the gap between the development of fundamental cryptographic algorithms and their use in commercial off-the-shelf technology.
