NSA have a master key to backdoor in NIST standard?

It’s sort of suspicious when the NSA champions any standards.
But when independent researchers found that the random number generation by the DUAL_EC_ERBG needed a fix set of numbers to generate the elliptic curve that in turn generates the random number? It became very intriguing on if this was not only a weakness but a backdoor.
Basic idea? Anyone that owns this set of master key numbers can take anything generated by this algorithm and decode it. From a cryptography standpoint, this is a big no-no, and screams of strangeness.
Am I surprised if the NSA holds the master key? Not at all. After the hoopla from the recent domestic spying incidence with the whistleblower, it’s really shouldn’t be. But there are some things that you just have to be a little more coy about if you’re going to hold the keys to the castle (assuming they do). Either way, you can view it in two fashions. One is that the NSA is doing their jobs and keeping track of information that could potentially protect our state of government if they do indeed hold the cards. The other is that, it’s good that independent researchers found this flaw in the algorithm since it would have been exploited somewhere else down the line if it wasn’t an actual NSA backdoor.
