Ensuring quantum-secured communications

Ai‐Dong Zhu, Yan Xia, Qiu-Bo Fan +1 more

We propose the schemes of quantum secure direct communication based on a secret transmitting order of particles. In these protocols, the secret transmitting order of particles ensures the security of communication, and no secret messages are leaked even if the communication is interrupted for security. This strategy of security for communication is also generalized to a quantum dialogue. It not only ensures the unconditional security but also improves the efficiency of communication.

The quantum secure communication is still in the early stages of implementation. The proposal of Quantum Key Distribution (QKD), while theoretically ensuring unconditional security in key distribution, presents practical challenges in the described communication scenarios. For instance, there are issues such as low key-distribution efficiency and the inability to achieve end-to-end identity authentication. In this paper, we have established a distributed quantum secure communication identity authentication system. We achieve end-to-end identity authentication and encrypted communication between communication terminals through a distributed authentication framework. At the same time, we utilize blockchain for storing transaction information. Blockchain, with its features of immutability, resistance to single points of failure and data corruption, and transparency, ensures that transaction information is publicly transparent and can be queried at any time. This design guarantees the tamper-proof nature of transaction information, thereby ensuring the uniqueness of the allocated keys and enhancing the security of the keys.

The article discusses the issues of information security in the aspect of developing a model of legal regulation of quantum communications. It is proved that quantum communications are a new method of information protection capable of ensuring information security in the context of a quantum threat. The development of quantum communications in Russia should be carried out on the basis of comprehensive regulation, including both the legal regulation of quantum communications and the legal regulation of quantum information security. Within the framework of this legal model, the necessity of implementing a system of legal measures that contribute to achieving a high level of information security is shown.
