Abstract

The invention discloses an arbitration quantum signature design method based on Grover iterative and flexible tracking. The design uses a Grover search algorithm to realize that when a signature dispute occurs, the arbitration management party can find the signer of the problematic signature. During the arbitration process, the arbitration management system negotiates with each signature participant to obtain the final key, find the signer of the problem signature, and avoid the direct "public" mechanism of the arbitration group signature. The present invention is characterized in that a complete arbitration signature verification system is established, and the arbitration management system can choose whether to disclose the identity of the signature signer of the problem, which has flexible traceability and fairness.
