Ultra-low-cost True Randomness

Posted by CmdrTaco on from the and-a-damn-fine-hack dept.

Cryptocrat writes "Today I blogged about a new method for secure random sequence generation that is based on physical properties of hardware, but requires only hardware found on most computer systems: from standard PCs to RFID tags." Basically he's powercycling memory and looking at the default state of the bits, which surprisingly (to me anyway) is able to both to fingerprint systems, as well as generate a true random number. There also is a PDF Paper on the subject if you're interested in the concept.

    Randomness is definable.

    Why, take a look at this Wikipedia link. You can never tell whether it represents the truth or some crackpot's claim to it or just some troll's malicious vandalism.

    Voila! Randomness!

    Wow, that actually makes sense. I'll bet you cheated and RTFA, didn't you?
