"note: I did not break the official algorithm. I do not know the secret value used to compute the Q constant, and thus cannot break the default implementation. Only NSA (and people with access to the key) can exploit the PRNG weakness." The second secret value is what folks are interested in: http://www.schneier.com/blog/archives/2007/11/the_strange_sto.html and http://blog.cryptographyengineering.com/2013/09/the-many-flaws-of-dualecdrbg.html.

Claiming that giants like MS would go out of business if it got out that they were working with the NSA is completely naïve.On 5/29/14, 4:13 PM, "Mike Cramer" <mike.cramer () outlook com> wrote: I think it¹s more important to have rational discussions. This isn¹t the first time Microsoft has been Œrumored¹ to have backdoors in Windows for the US Government. These rumors have been perpetuated for years. While I don¹t know how long you¹ve been in the industry, it¹s something I recall even being 14 years old and sitting on IRC and having people discuss. The reality now, just as then, is that these are unsubstantiated. A more apt description about the cooperation between the US Government and Microsoft I think falls back onto our old pals ³Alice and Bob². I¹m sure you may recall these names from any sort of discussion about PKI. What people seem to forget in all of these discussions is that Microsoft is Bob. (Microsoft Bob? :P) No amount of encryption, protection, secret keying is going to protect you when one party is going to hand over the information to 3rd parties to review. Based on my Alice and Bob comment above, it¹s reasonable to assume that the encryption itself is 100% fine, so as long as you believe that Bob will never divulge the information you¹ve disclosed. Through all of these discussions surrounding Bitlocker across multiple forums nobody has brought up the fact that Bitlocker in Windows 8 allows you to store recovery key information in OneDrive/²The Cloud². Why bother writing in backdoors to the software when the keys are readily available with a warrant? There are a million and one ways to get access to the information and the absolutely most difficult, most costly, and most potentially damaging is the one people are jumping to first. If it were ever revealed that Microsoft purposefully weakened its encryption systems to allow the NSA access to any Windows device, then it would be the end of the organization. They¹re just not that dumb.
