Title:
Security analysis on an electronic voting scheme based on a quantum ring signature
Authors: Xin Xiangjun, Qiu Shujing, Li Chaoyang, Li Fagen
Abstract:Recently, Qiu et al. proposed a quantum voting scheme based on the ring signature (International Journal of Theoretical Physics, 60: 1550–1555(2021)), in which the signer and verifier only need measure the received particles with Z-basis and perform some classical simple encryption/decryption operations on the classical message. Although their scheme is very efficient, it cannot resist against the eavesdropping attacks and forgery attack. In this paper, first, the eavesdropping attacks on Qiu et al.’s scheme are proposed. Second, we show the forgery attack on their scheme. According to the security analysis, it follows that, when desiring the quantum ring signature scheme, we should carefully analysis its security against eavesdropping attacks and forgery under chosen message attack.
