Zero-Knowledge Object-Comparison System Demonstrated in Nature Communications

CVT

Future arms control agreements may require trusted verification mechanisms aimed at confirming the authenticity of items presented as nuclear warheads. In the last five years, our team has been pioneering a warhead verification approach based on the cryptographic concept of zero-knowledge proofs. This approach could allow the authentication of nuclear warheads without sharing any design information.

The original idea was published in Nature in June 2014. Since then, we have been working on the development of a zero-knowledge object-comparison system and the procedures for its use in nuclear warhead inspections. The demonstration of such a system is now outlined in a Nature Communications article published on September 20, 2016.

Alex Wellerstein has written a nice story about our work and experiments in the New Yorker.
