A Public Key Arbitration Quantum Signature Protocol Based on Quantum Block Encryption

Abstract

The invention discloses a public key arbitration quantum signature protocol based on quantum block encryption, which belongs to the technical field of quantum security communication, including quantum key sharing among signers, receivers and arbitrations through quantum key distribution; signers Prepare two quantum messages and a quantum signature, send a quantum message to the receiver, and send the quantum signature to the arbitration; the receiver performs quantum signature verification under the constraints provided by the arbitration. The protocol provided by the invention can not only guarantee safety, but also has better practical application value.

Description

technical field [0001] The invention relates to the technical field of quantum secure communication technology, in particular to a public key arbitration quantum signature protocol based on quantum block encryption. Background technique [0002] With the rapid development of communication technology and computer technology, electronic information has become a part of people's daily work and life. Informatization has expanded the way for people to understand the world, and it has also provided infinite possibilities for people to transform the world. However, unprecedented security threats are also intensified along with the deepening of informatization, so it is particularly urgent to explore and study theories and technologies to ensure information security. [0003] Digital quantum signature is the core technology to realize identity authentication and protect data integrity, and is the key theoretical basis for implementing information system access control and secure e-c...
