On September 9, 2013, following the Snowden leak, and the New York Times report on the backdoor in Dual_EC_DRBG, the National Institute of Standards and Technology (NIST) ITL announced that in light of community security concerns, it was reissuing SP 800-90A as draft standard, and re-opening SP800-90B/C for public comment. NIST now "strongly recommends" against the use of Dual_EC_DRBG, as specified in the January 2012 version of SP 800-90A.http://csrc.nist.gov/publications/nistbul/itlbul2013_09_supplemental.pdf The discovery of a backdoor in a NIST standard has been a major embarrassment for the NIST.
