Cryptanalysis and improvement of several quantum private comparison protocols
Zhao-Xu Ji, Pei-Ru Fan, Huan-Guo Zhang +1
Recently, Wu et al. [Int. J. Theor. Phys. 58, 1854, (2019)] found a serious information leakage problem in Ye and Ji's quantum private comparison protocol [Int. J. Theor. Phys. 56,…

Greenberger-Horne-Zeilinger-based quantum private comparison protocol with bit-flipping
Zhaoxu Ji, Peiru Fan, Huanguo Zhang +1
By introducing a semi-honest third party (TP), we propose in this paper a novel QPC protocol using (n+1)- qubit (n \ge 2) Greenberger-Horne-Zeilinger (GHZ) states as information ca…
