NSA Claims On Breaking Diffie-Hellman Key Exchange Through Precomputation

The Internet is abuzz with this blog post and paper, speculating that the NSA is breaking the Diffie-Hellman key-exchange protocol in the wild through massive precomputation.

I wrote about this at length in May when this paper was first made public. (The reason it's news again is that the paper was just presented at the ACM Computer and Communications Security conference.)
