Abstract

Recently, Lin et al. proposed a novel quantum private comparison protocol without a third party (Quantum Inf. Process. 13:239–247, 2014). This paper points out two security loopholes in Lin et al.’s protocol, in which one dishonest party can disclose the other’s private information without being detected and the comparison result can be manipulated completely by either party. In addition, improvements are proposed to avoid these loopholes.
