Many people have pointed out, perhaps correctly, that strong crypto could mean the end of the line for many of the workers at the NSA. If I was in charge of the NSA, I would argue to my budget-dispensing superiors that all of the strong crypto just meant that I needed a bigger budget to scan for data. So the terrorists get crypto terminals? Well, they probably won't have a Tempest class machine so there is plenty of SIGINT that can still be done. There are plenty of opportunities to target people and their communications links with localized bugs. It just requires some more money. I've often wondered whether the NSA's presumed approach of acting as a huge vacuum cleaner for data was the best way of gathering intelligence. It may have been in the 1960's and earlier when transmission rates were relatively expensive and people didn't call long distance unless their was a death in the family. Now, though, the sheer volume of data has exploded. Vaccuumming it all in and sorting it out in the buildings at Fort Meade must be much less cost effective-- no matter how many voice recognition computers that they have. Today, information is much, much cheaper than it used to be. Intelligence is just as expensive as ever. Incidentally, Bill Safire wrote a great piece on this a year or so ago. He argued that it was time for the Spy agencies to go back to Mata Hari type shenanigans because the magic window of SIGINT was about to be closed again. If anyone could dig it up, I would appreciate the reference. -Peter Wayner
