Duh?!? Did you think otherwise?
Sorry to overstate the obvious, but did anyone really think that NIST would be completely independent from NSA influence?
They both get their budgets from the same place and even if NIST did not contact the NSA, the moment that one of NIST's egotistical PHD's wrote an email on or published a whitepaper on encryption or random number generation; how long do you think it took for the NSA to show up on their doorstep telling them they had to provide a backdoor to the random number algorithim????
Can you say global keyword search? Anyone want to bet who's already got the keys to RNG for Microsoft products?
