Comment Random Number Generation (Score 1) 106
So from what I am guessing - they are referring to using the radioactive decay of the materials for true random number generation. This concept isn't new - the unpredictability of radioactive decay has been a know source of "truly random" numbers. The article infers that it could use this to generate a key that could be shared with an external authentication mechanism - but you could do this with any random number source. You'd think they would have mentioned something like "quantum entanglement between the weapon and the president" (which might have been interesting) - but no.
