“…In the future, we will concentrate on studying how to design the semiquantum summation protocol feasible over other noisy quantum channels, such as the collective-rotation noise channel, the amplitude damping channel, etc. As two classical communicants can know each other's private binary sequence, this protocol cannot be directly applied into SQPC [27,[34][35][36][37][38]. In the future, we will also study how to apply semiquantum summation into the other semiquantum secure computation, such as SQPC, semiquantum key agreement (SQKA) [39][40][41], etc.…”

In this paper, we propose a two-party semiquantum summation protocol, where two classical users can accomplish the summation of their private binary sequences with the assistance of a quantum semi-honest third party (TP). The term 'semi-honest' implies that TP cannot conspire with others but is able to implement all kinds oof attacks. This protocol employs logical qubits as traveling particles to overcome the negative influence of collective-dephasing noise and needn't make any two parties pre-share a random secret key. The security analysis turns out that this protocol can effectively prevent the outside attacks from Eve and the participant attacks from TP. Moreover, TP has no knowledge about the summation results.

“…With the assistance of the TP, the two protocols can also compare the equality of privacies for N (N ≥ 2 ) participants. Since then, various two-party [11][12][13] and multi-party QPC protocols have been proposed [14][15][16][17]. In 2018, Ye et al proposed two novel multi-party quantum private comparison protocols for size relation comparison by using d-level single-particle states.…”

A feasible multi-party quantum private comparison (MQPC) protocol based on d-dimensional Bell states was proposed. In the protocol, all participants can independently encrypt their privacies and send them to a semi-honest quantum third party (TP) through authenticated channels. Then, the TP can determine the size relationship among all participants’ privacies without gaining access to the private information. We verified correctness and effectiveness of the proposed protocol with some examples. In addition, compared with other similar protocols, it is not necessary to perform unitary operation on particles and only single-particle measurement is required. Furthermore, the relatively high qubit efficiency is promised. The security analysis verifies that the proposed protocol can counteract external and internal attacks in theory.

“…Based on the consideration of reducing quantum resources in the process of key distribution, the concept of semi-quantum key distribution (SQKD) [24] has been proposed and extended into semi-quantum cryptography, such as semi-quantum secret sharing (SQSS) [25,26], semi-quantum secure direct communication (SQSDC) [27][28][29], semi-quantum digital signature (SQDS) [30], semi-quantum private comparison (SQPC) [31][32][33][34][35], and semi-quantum key agreement (SQKA) [36,37]. In 2007, Boyer et al proposed the first SQKD protocols: BKM07 [24], which place a further restriction on the classical user.…”

Semi-quantum key distribution is based on the basic principle of quantum mechanics, which allows a classical user and quantum user to use information theory to have a secure shared key. In 2021, our research group proved the first proof-of-principle experimental demonstration of semi-quantum key distribution and verified its feasibility. Due to the limitations of existing science and technology, the experimental system still features a combination of multiphoton signal source and loss in the transmission line. This makes semi-quantum key distribution as susceptible to a photon-number splitting attack as quantum key distribution, leading to limitations of secure transmission distance. It seems that practical single-state semi-quantum key distribution can overcome photon-number splitting attack due to the SIRT bits (also known as the “sifted key”). However, its dual-channel feature still opens up an observation window to Eve. We present two joint photon-number splitting attacks suitable for a single-state semi-quantum key distribution system and show that through the joint photon-number splitting attack, Eve can obtain key information without being detected by Alice or Bob.
