Zero-knowledge protocol

PPPL intern Joseph Labrum helped build components for a “zero knowledge” system that may have applicability to future nuclear arms control agreements

Joseph Labrum spent his summer internship building components to upgrade an experiment that successfully compared physical objects without learning anything about the objects themselves. Such a “zero-knowledge protocol” system is a promising first step toward a technique that could possibly be used in future disarmament agreements, pending the results of further development, testing, and evaluation. While important questions remain, it might have potential application to verify that nuclear warheads are in fact true warheads without revealing classified information.

Rob Goldston, Alex Glaser and Boaz Barak named among Foreign Policy magazine’s 100 top global thinkers

Editors of Foreign Policy magazine have named fusion physicist Rob Goldston, a Princeton University professor of astrophysical sciences and former director of PPPL, to its list of  “100 Leading Global Thinkers of 2014.” The recognition, made Nov. 17 at a celebration in Washington, D.C., honored Goldston for his contributions to the field of nuclear arms control.
