Quantum identity authentication protocol based on three‐photon quantum error avoidance code in edge computing

Summary Information security protection is always one of very significant and fundamental issues in edge computing, generally including cryptography, authentication, intrusion detection, privacy protection, and other technologies, and so forth. Quantum authentication is one of the latest extensions of authentication technology in quantum field. So far, most of the quantum identity authentication protocols proposed are based on noise‐free environments. However, due to the existence of quantum noise in quantum channels is inevitable, the noise immunity is very important to quantum identity authentication. In this article, a novel quantum identity authentication protocol based on three‐photon error avoidance code is proposed. In this protocol, quantum information is encoded on the noiseless subsystem, so the protocol can effectively resist on the interference of noise in the quantum channel to information transmission. The comprehensive analysis of antinoise performance and the security analysis on various eavesdropping attacks shows that the new protocol proposed in this article has not only good antinoise performance but also good security.
