“…It can enable n participants to jointly calculate a summation without revealing any participant’s secret to others. Quantum summation can be applied to a variety of fields, such as quantum voting [ 15 , 16 , 17 , 18 ], quantum anonymous ranking [ 19 , 20 ], and quantum private equality comparison [ 21 , 22 , 23 ]. Designing efficient and practical quantum summation protocols is thus significant.…”

In this paper, we propose a secure multi-party summation based on single photons. With the help of a semi-honest third party, n participants can simultaneously obtain the summation result without revealing their secret inputs. Our protocol uses single photon states as the information carriers. In addition, each participant with secret input only performs simple single-particle operators rather than particle preparation and any complex quantum measurements. These features make our protocol more feasible to implement. We demonstrate the correctness and security of the proposed protocol, which is resistant to participant attack and outside attack. In the end, we compare in detail the performance of the quantum summation protocol in this paper with other schemes in terms of different indicators. By comparison, our protocol is efficient and easy to implement.

“…In 2009, Yang and Wen [19] proposed the first quantum private comparison (QPC) protocol, which can compare the equality of private inputs from two different users under the condition that none of their private inputs will be leaked out. Since then, scholars have designed abundant QPC protocols with different quantum states, such as the ones with single particles [20,21], Bell states [22][23][24], GHZ states [25,26], cluster states [27], χ -type entangled states [28], etc. The above QPC protocols require all users to have complete quantum capabilities, which may incur high costs in practice.…”

In this paper, a novel semiquantum private comparison (SQPC) protocol based on single kind of Bell states is proposed, which allows two classical parties to judge the equality of their private inputs securely and correctly under the help of a semi-honest third party (TP) who possesses complete quantum capabilities. TP is allowed to misbehave on her own but cannot conspire with anyone else. Our protocol needs none of unitary operations, quantum entanglement swapping or the reordering operations. Moreover, our protocol only needs to prepare single kind of Bell states as initial quantum resource. Detailed security analysis turns out that our protocol is secure against various outside and participant attacks. Compared with most of the existing SQPC protocols based on Bell states, our protocol is more feasible in practice.

“…So far, several protocols for QPC have been presented. There are protocols based on Bell states, [24][25][26][27][28][29] GHZ entangled states, [30][31][32][33][34] entanglement swapping, [35][36][37][38] superdense coding, [39] etc. To take more participants into comparison, the multi-party quantum private comparison (MQPC) has been firstly proposed by Chang et al in 2013.…”

“…They are protocols based on the single-particle [41][42][43][44][45][46] and protocols based on the multiparticle. [26][27][28][29][30][31] Most of the multi-particle-based protocols are using entangled states. In 2012, Wen et al proposed the QPC protocol based on Bell states.…”

In this paper, we propose an efficient quantum private comparison protocol firstly based on one direction quantum walks. With the help of one direction quantum walk, we develop a novel method that allows the semi-honest third party to set a flag to judge the comparing result, which improves the qubit efficiency and the maximum quantity of the participants’ secret messages. Besides, our protocol can judge the size of the secret messages, not only equality. Furthermore, the quantum walks particle is disentangled in the initial state. It only requires a quantum walks operator to move, making our proposed protocol easy to implement and reducing the quantum resources. Through security analysis, we prove that our protocol can withstand well-known attacks and brute-force attacks. Analyses also reveal that our protocol is correct and practical.
