Secure quantum private comparison
Yu‐Guang Yang, Weifeng Cao, Qiaoyan Wen · Physica Scripta · 2009
We propose a two-party quantum private comparison protocol using single photons, in which two distrustful parties can compare whether their secrets are equal with the help of a third party (TP). Any information about the values of their respective secrets will not be leaked out even with a compromised TP. Security is also discussed.
