Special Issue Information

Dear Colleagues,

Quantum communications have achieved information theoretic security for cryptographic tasks such as key distribution, secure direct communication, true random number and so on. Further, for a great multitude of other cryptographic tasks, quantum communications can provide a higher level of security which is independent of computational complexity, as well as lower communication complexity. Quantum key distribution is more mature in both theory and technology than other types of quantum communication protocols. However, other types of protocols also need to be developed to enrich the capabilities of quantum communication.

This Special Issue focuses on the technologies of quantum communication protocols, especially those in which the participants do not trust each other, and the technologies to solve practical security problems in a variety of quantum communications, including—but not limited to—quantum private query, quantum secret sharing, quantum coin flipping, quantum signature, quantum voting and so on.

This issue also focuses on the applications of quantum key distribution to solve other cryptographic problems and the applications of any other kind of quantum communication protocols to solve practical problems in network communication, financial activities and so on.

I look forward to receiving your contributions.

Quantum sealed-bid auction (QSA) is a special form of transaction with significant applications in the economic and financial fields. Using a unique set of locally indistinguishable orthogonal product (LIOP) states, we propose a new QSA protocol in this paper. In the protocol, the bid message is encoded as a quantum sequence of LIOP states, and the different particles of LIOP states are transmitted separately. Even though an attacker obtains a portion of the particles, they cannot recover the entire bid message because of the local indistinguishability of LIOP states. Once the auctioneer announces the winner’s bid, all bidders are able to confirm the authenticity of their bid. With the help of a semi-honest third party, collusion between the auctioneer and a malicious bidder can be discovered. Finally, our protocol is capable of meeting all requirements for secure sealed-bid auctions through security and completeness analysis. Additionally, the proposed protocol does not require any entangled resources and complicated operations, so it can be easily implemented in practice. Full article

In quantum secure multi-party summation protocols, some attackers can impersonate legitimate participants in the summation process, and easily steal the summation results from the participants. This is often overlooked for existing secure multi-party summation protocols, thus rendering them insecure. Based on commutative encryption, a quantum secure multi-party summation protocol with identity authentication is proposed in this paper. In the protocol, each participant encodes a secret integer on photons via unitary operations. At the same time, a one-way hash function technique with a key is utilized to perform identity authentication operations for each participant. Finally, the summation is calculated with the help of a semi-trusted third party. The analysis of the protocol shows that the proposed protocol is correct and resistant to common and impersonation attacks. Compared to related protocols, the use and measurement of single photons makes the protocol easier to implement into existing technology. Furthermore, the simulation experiments on the IBM Q Experience cloud platform demonstrate the effectiveness of the presented protocol. Full article
