Uncrackable code for nuclear weapons

Mark Hart, a scientist and engineer in Lawrence Livermore National Laboratory’s (LLNL) Defense Technologies Division, has developed a new approach for ensuring nuclear weapons and their components can't fall prey to unauthorized use. The beauty of his approach: Let the weapon protect itself.

“Using the random process of nuclear radioactive decay is the gold standard of random number generators,” said Mark Hart, a scientist and engineer in Lawrence Livermore National Laboratory’s (LLNL) Defense Technologies Division. “You’d have a better chance of winning both Mega Millions and Powerball on the same day than getting control of IUC-protected components.”
