“…Eve acts as an overseer. Alice, Bob, Charlie, David, and Eve share the nine-qubit entangled channels given in Equation (3), where the qubits (1,2,3) of the channels belong to Alice and are marked with bits a 0 , a 1 , and a 2 respectively, and Eve owns qubits (4), marked with e. The qubits (5,6) are in David's hands, and they are labeled d 1 and d 2 ; the qubits (7) and (8,9) belong to Bob and Charlie, respectively, and are labeled b and c 1 and c 2 , respectively. We can also rewrite the channel given in Equation (3) as follows:…”

With the continuous development of the Internet of Things (IoT) technology, the industry’s awareness of the security of the IoT is also increasing, and the adoption of quantum communication technology can significantly improve the communication security of various devices in the IoT. This paper proposes a scheme of controlled remote quantum state preparation and quantum teleportation based on multiple communication parties, and a nine-qubit entanglement channel is used to achieve secure communication of multiple devices in the IoT. The channel preparation, measurement operation, and unitary operation of the scheme were successfully simulated on the IBM Quantum platform, and the entanglement degree and reliability of the channel were verified through 8192 shots. The scheme’s application in the IoT was analyzed, and the steps and examples of the scheme in the secure communication of multiple devices in the IoT are discussed. By simulating two different attack modes, the effect of the attack on the communication scheme in the IoT was deduced, and the scheme’s high security and anti-interference ability was analyzed. Compared with other schemes from the two aspects of principle and transmission efficiency, it is highlighted that the advantages of the proposed scheme are that it overcomes the single fixed one-way or two-way transmission protocol form of quantum teleportation in the past and can realize quantum communication with multiple devices, ensuring both security and transmission efficiency.

“…On the other hand, some of the studies focus on other perspectives that affect digital signatures, such as the digital signature algorithm [29], the quantum signature method [30], digital signature standards [31], security [32], etc. For example, security is the most important issue for digital signatures.…”

Today, the interest and the needs of all sectors for digital signatures are increasing day by day. The next approvals in businesses cannot take place without the previous approvals, which follow one after the other, such as a chain of transactions. For this reason, the approval (that is, the signature of a relevant unit) should be carried out as soon as a document is received and immediately forwarded to the next unit. Digital signatures are needed to carry out business transactions quickly and reliably. The use of digital platforms and systems, which are indispensable parts of digital transformation, can be achieved primarily with awareness and understanding of their importance. However, a digital signature awareness scale was not found in the literature. Therefore, in this study, a new scale was developed which can be used to determine the digital signature awareness of people and it is hoped to eliminate this deficiency in the current literature. The developed scale consists of two dimensions: awareness and benefits. The study was designed as descriptive research and 567 participants voluntarily participated in the study. Factor analysis and descriptive analysis methods were used to analyze the collected data. In line with the statistical analysis results, it has been observed that the developed scale provides validity and reliability features and is qualified to be used in scientific research to determine the awareness of people about digital signatures. With the digital signature scale, which is thought to fill the gap in the literature, it is hoped that the digital signatures awareness of people in developing countries, and in particular in Cyprus will be determined, and it is also hoped that people will be encouraged to use digital signatures after necessary training.

“…This method can also be used in other AQS schemes. In 2022, Huang et al [24] proposed an improved identity based public key quantum signature scheme. In this scheme, the signer uses her key and the verifier's secret parameter to generate a quantum signature, and the signer and verifier do not need to exchange keys before signing the message, making the scheme highly efficient.…”

With the rapid development of computer and internet technology, quantum signature plays an extremely important role in modern secure communication. Quantum homomorphic aggregate signature, as an important guarantee of quantum signature, plays a significant role in reducing storage, communication, and computing costs. This article draws on the idea of quantum multi-party summation and proposes a quantum homomorphic aggregate signature scheme based on quantum Fourier transform. Our scheme uses n-particle entangled states as quantum channels, with different particles of each entangled state sent separately. This ensures secure transmission of signatures and messages with fewer entangled particles during transmission, further improving the efficiency of quantum signatures. Meanwhile, our scheme generates private keys for each participating party by randomly constructing key generation matrixes. Different signers perform quantum Fourier transforms and basis exchange operations on entangled particles based on different messages and private keys to generate signatures. In addition, the aggregator does not need to measure and verify the signature particles after receiving signatures from different signers, and the group addition operation process has additive homomorphism. Security analysis shows that our scheme has unforgeability, non-repudiation, and can resist various attacks such as entanglement measurement attacks, intercept-resend attacks, private key sequence attacks, and internal attacks by aggregator.
