So, as we all know, Dual_EC_DRBG contains an NSA back door. At this point, there is no reason to call it a "potential" or even an "alleged" back door; the presence is obvious even to the NY Times. As we also know, RSA BSAFE has been using Dual_EC_DRBG by default, with a justification so stupid it can only be translated as "because NSA paid us to". With hindsight, NSA should have ceased supporting the Dual_EC_DRBG algorithm immediately after security researchers discovered the potential for a trapdoor. In truth, I can think of no better way to describe our failure to drop support for the Dual_EC_DRBG algorithm as anything other than regrettable. The costs to the Defense Department to deploy a new algorithm were not an adequate reason to ... NIST SP 800-90A Rev.1: This is essentially NIST SP 800-90A with Dual_EC_DRBG removed, and is the withdrawn standard's replacement. ANSI X9.17-1985 Appendix C; ANSI X9.31-1998 Appendix A.2.4; ANSI X9.62-1998 Annex A.4, obsoleted by ANSI X9.62-2005, Annex D (HMAC_DRBG) A good reference is maintained by NIST. And like Dual_EC_DRBG, it provides no documentation for how or why this number was chosen. Now as Vitalik pointed out, even if the NSA knew of a specific elliptic curve with vulnerabilities, it still should have been near impossible for them rig the system due to the fact that brute-forcing a hash function is not feasible. 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…
