Improvements on "Secure multi-party quantum summation based on quantum Fourier transform"
Cai Zhang, Mohsen Razavi, Zhewei Sun +1
Recently, a quantum multi-party summation protocol based on the quantum Fourier transform has been proposed [Quantum Inf Process 17: 129, 2018]. The protocol claims to be secure ag…
Multi-party quantum summation based on quantum teleportation
Cai Zhang, Mohsen Razavi, Zhiwei Sun +2
We present a secure multi-party quantum summation protocol based on quantum teleportation, in which a malicious, but non-collusive, third party (TP) helps compute the summation. In…
Three-party quantum private comparison of equality based on genuinely maximally entangled six-qubit states
Cai Zhang, Zhiwei Sun, Xiang Huang +1
We propose a new three-party quantum private comparison protocol using genuinely maximally entangled six-qubit states. In our protocol, three participants can determine whether the…
Cryptanalysis of the efficient two-party quantum private comparison protocol with decoy photons and two-photon entanglement
Zhiwei Sun, Dongyang Long
We analyze the security of the efficient two-party quantum private comparison protocol with decoy photons and two-photon entanglement. It is shown that the compromised third party…
Improving the security of arbitrated quantum signature protocols
Zhiwei Sun, Ruigang Du, Dongyang Long
Arbitrated quantum signatures (AQS), for signing quantum message, have been proposed. It was claimed that the AQS schemes could guarantee unconditional security. However, in this p…
Semi-quantum key distribution protocol using Bell state
Zhiwei Sun, Ruigang Du, Dongyang Long
A quantum key distribution protocol with classical Bob based on polarization entangled photon pairs is presented. It approximates a single photon and exploited the inherent randomn…
