Zero-Knowledge Object-Comparison System Demonstrated in Nature Communications


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.


NFL-winners Not only was the 2013 Nobel Peace Prize announced today, we are also happy to report that M. V. Ramana and Zia Mian were recognized this week for their work on global security issues. M. V. Ramana together with R. Rajaraman (Jawaharlal Nehru University, New Delhi) has received the American Physical Society’s 2014 Leo Szilard Award “for outstanding contributions to promote global security issues, through critical analyses of nuclear weapons and nuclear energy programs in India and associated risks in the subcontinent, and efforts to promote peace and nuclear security in South Asia though extensive engagements and writings.” The Leo Szilard Award was established to recognize outstanding accomplishments by physicists in promoting the use of physics for the benefit of society in such areas as the environment, arms control, and science policy. Zia Mian has been awarded the 2014 Linus Pauling Legacy Award on the occasion of the fiftieth anniversary of Linus Pauling’s receipt of the Nobel Peace Prize. The award was established in 2001 to honor individuals who have achieved in areas of interest to Linus Pauling.
