There are multiple data points suggesting the NSA is/was ahead of public researchers. There's the sbox changes to DES in the 70's when differential cryptanalysis wasn't publicly discovered till the 80's. The revisions between SHA-0 and SHA-1 (the attack the changes prevent weren't found for at least 5 years). The Dual EC DRBG random number generator they supplied to NIST that many people suspect of being compromisable by NSA etc.

- ktsmith 13y agoI would count it's development and publication as another example of the NSA being a bit ahead as it very much looks like they developed an algorithm in secret with a backdoor. I would count the fact that the public found it (after a few years) a point for public crypto research.
