Largest Privately Owned Supercomputer
GORMUR writes "IBM has launched its Watson Blue Gene system, the largest privately owned supercompuer seen by the press. The super computer is described reaching a whopping 91.29 teraflops. IBM has plans on giving Academic researchers access to some computing time. Some more info can be found the IBM site. All this makes you wonder what other supercomputers are out there, not known to the press, and if it's time to increase the size of your private key and strengthen your encryption."
What's really bad (or good, depending on one's point of view, I assume) about the NSA is not just the computing power they likely wield (they're the biggest consumer of electric power in the entire state of Maryland, so they probably do have some big iron there on site), but also the theoretical power in the form of mathematicians. The NSA is the single biggest employer of mathematicians in the world, and it's probably safe to say that they are at least a couple of years ahead of the rest of the world as far as cryptography and cryptanalysis is concerned.
Remember, for example, that the NSA invented public-key cryptography before Diffie and Hellman did; or remember that they made some changes to the S-boxes for DES when it first was submitted that noone understood back then but that did turn out to eliminate weaknesses in the original design later on.
I dare say that this theoretical advantage is actually more important than the pure number crunching power they wield. There's virtually no limit on the computing power you can buy if you have enough money at your disposal (for example, there is no real reason why IBM shouldn't be able to build a system roughly a thousand times as fast as the BG/W system if someone paid the necessary 40 billion dollars), but you can't buy advances in mathematics with money.

Encryption Schmichion
We should be more concerned about someone with a Knoppix live-cd or something along those line. That thing has thus far given me unfettered access to more than 98% of the computer system into which I have booted it. For those that had no CD-rom you can just use an USB cd-rom. The only trouble you might encounter is if the BIOS is not set to boot off the CD-rom first and it has a password
