EXPERIMENTAL RELATIVISTIC ZERO-KNOWLEDGE PROOFS

In this work, we report the experimental realisation of such a
zero-knowledge protocol involving two separated verifier-prover pairs.
Security is enforced via the physical principle of special
relativity, and no computational assumption (such as the existence of
one-way functions) is required. Our implementation exclusively relies
on off-the-shelf equipment and works at both short (60m) and long
distances (>400m) in about one second. This demonstrates the practical
potential of multi-prover zero-knowledge protocols, promising for
identification tasks.
