On Zero-Knowledge Proofs over the Quantum Internet
share
This paper presents a new method for quantum identity authentication (QIA) protocols. The logic of classical zero-knowledge proofs (ZKPs) due to Schnorr is applied in quantum circuits and algorithms. This novel approach gives an exact way with which a prover P can prove they know some secret without transmitting that directly to a verifier V by means of a quantum channel - allowing for a ZKP wherein an eavesdropper or manipulation can be detected with a `fail safe' design. With the anticipated advent of a `quantum internet', such protocols and ideas may soon have utility and execution in the real world.
