The NSA's Information Assurance wing considers itself responsible for the security of classified US Government systems only—specifically not unclassified US Gov

The NSA's Information Assurance wing considers itself responsible for the security of classified US Government systems only—specifically not unclassified US Government systems, or any civilian systems whatsoever, which they feel falls under NIST's domain. But yes, it's much smaller than their SIGINT wing, and yes, I also feel that having both teams under the same roof (so to speak) is not just an 'equities problem' - it's a full-scale irreconcilable conflict of interest. You might feel that surely the NSA wouldn't backdoor their own stuff? But no: there they are, actually using Dual_EC_DRBG even in their own most trusted crypto hardware - in, I presume, the firm belief that "nobody but us" has the private key to use the backdoor. Which seems somewhat reckless in light of a working distinguisher and how very fragile (EC)DSA is… and a stark reminder of how the recent return to talk of backdoors - sorry, "front doors" or "secure golden keys", because they want to control the language to frame the debate in the way they want - are so much bullshit, and the only reasonable discussion we can have about things which undermine all of our collective security is one where the people who are asking for such idiotic things to - they think - make their jobs easier should kindly shut the fuck up. Ahem. GCHQ over here have the exact same issue with CESG and the MoD CRYPTO group versus the COMINT/ELINT/SIGINT bulk of their mission. GCHQ have even selected their own suppliers and political and other infrastructure for targeted surveillance in some cases! So for those who choose to try to work with them - surprise! - that doesn't mean they're not also working against you too. It just gives them another angle.
