If true, it is seriously disturbing. The KGB is presumably the only
entity on earth with cryptography expertise in the range of the NSAs.
The notion that in spite of the advances of the last twenty years it
is still possible for a few years technical lead to make that much of
a difference likely means that what we don't know about conventional
cryptosystems is likely still extremely important.

I had been running on the assumption for a while that the NSA was
slowly losing its capacity to break codes as ones with inherently
better and better theoretical underpinnings arrived. If the story is
true, it means that the NSA can break some classes of conventional
cryptosystems very fast -- fast enough to be of use in this case, for
instance.

We are all very dependent on things like MD5 and IDEA, which may or
may not actually be secure. We should bear this in mind.
