PPPL and Princeton demonstrate a novel physical technique that may have applicability to future nuclear disarmament agreements

screen-shot-2016-09-21-at-2-36-01-pmA system that can compare physical objects while potentially protecting sensitive information about the objects themselves has been demonstrated experimentally at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). This work, by researchers at Princeton University and PPPL, marks an initial confirmation of the application of a powerful cryptographic technique in the physical world.
