That's an interesting paper (I wasn't aware of it and I like their
approach; thanks for sharing) but I don't think its conclusions
contractict that quote from Ross Anderson's blog post. That merely
states that the NSA doesn't have a very fast way to break RSA-1024.

It is well possible that they are using an approach similar to the one
Bernstein and Lange describe to crack the RSA-1024 private keys of
prime targets.
