The U.S. standards agency that published FIPS 186-2 and SP 800-90A

The National Institute of Standards and Technology is the U.S. Commerce Department agency that publishes federal cryptographic standards. It adopted ECDSA in FIPS 186-2 in 2000, and on April 21, 2014 it removed the Dual_EC_DRBG generator from its draft random-number guidance, citing the lack of public confidence in the algorithm.
