The most popular incident of which is Dual_EC_DRBG. Dual Elliptic Curve Deterministic Random Bit Generator is an algorithm that was presented as a cryptographically secure pseudorandom number generator (CSPRNG) using methods in elliptic curve cryptography ( used in Bitcoin to create private and public key ). The Dual_EC_DRBG generator from NIST SP800-90A. Update 9/19: RSA warns developers not to use the default Dual_EC_DRBG generator in BSAFE. Oh lord. As a technical follow up to my previous post about the NSA's war on crypto, I wanted to make a few specific points about standards. In particular I wanted to address the allegation that… NSA kleptographic backdoor in the Dual_EC_DRBG PRNG . The Guardian and The New York Times have reported that the National Security Agency (NSA) inserted a backdoor into a PRNG of NIST SP 800-90A which allows the NSA to readily decrypt material that was encrypted with the aid of Dual_EC_DRBG. Back in 2007, Bruce Schneier reported on a backdoor found in NIST’s Dual_EC_DRBG random number generator: But today there’s an even bigger stink brewing around Dual_EC_DRBG. In an informal presentation (.pdf) at the CRYPTO 2007 conference in August, Dan Shumow and Niels Ferguson showed that the algorithm contains a weakness that can only be Dual_EC_DRBG internals. Dual_EC_DRBG is defined in NIST SP800-90A page 60. It is an algorithm generating an infinite number of pseudo-random sequences from a single seed, taken in the first step or after an explicit reseed. It is unfortunate that SP800-90A and the presentation from Microsoft use conflicting terminology (variable names).
