Application of quantum key distribution in intelligent security operation and maintenance of power communication networks

Hongnian Wen, Aixue Xu, Huijuan Qi

With the continuous development of power communication network and the improvement of intelligent degree, network security and operation and maintenance become more and more important. Therefore, this paper proposes a solution for intelligent security operation and maintenance of power communication network based on Quantum key distribution (QKD). QKD is an encryption technology based on the principle of quantum mechanics, which can realize secure Key exchange and resist attacks of traditional encryption algorithms. We use QKD technology to generate and distribute security keys for protecting communication and data transmission in power communication networks. The results show that the efficiency and accuracy of communication data acquisition, transmission, analysis and processing of the Artificial Intelligence for IT Operations system of the power communication network using the power Internet of Things technology are far higher than that of the traditional operation and maintenance technology, which improves the operation and maintenance accuracy of the power communication network by about 25%. The intelligent operation and maintenance system of the power communication network designed by the author, it effectively improves the communication data processing capability and the reliability of operation and maintenance results, and can meet the current practical engineering application requirements. This study provides an innovative solution for the secure operation and maintenance of power communication networks, which is of great significance for protecting the security and stable operation of power communication networks.

Research on the Commercial Cryptography Protection Framework for the Power Sector: A Roadmap from Legacy Cryptography to Post-Quantum Migration

Kaitian Huang, Yuan Pan

As the power industry's digital transformation accelerates, commercial cryptography as a core technical means to ensure the safe and stable operation of power systems, is facing unprecedented opportunities and challenges. This study focuses on the cryptography application scenarios across the generation, transmission, transformation, distribution, and consumption links of the power industry. It systematically analyzes the technical path for migrating from traditional cryptography applications to post-quantum computing-resistant cryptography applications, explores the implementation scheme of quantum key distribution (QKD) technology in internal communication networks, and discusses the application prospects of privacy-preserving computation technology for data services. The research indicates that the power industry has established a relatively sound commercial cryptography application system. However, against the backdrop of the looming threat of quantum computing, the security of traditional cryptographic algorithms will face severe challenges. By constructing a ‘traditional cryptography-post-quantum computing-resistant cryptography hybrid architecture’, deploying quantum key distribution (QKD) networks, and applying privacy-preserving computation technology for data services, the cryptographic security protection capability of power systems can be significantly enhanced. This study provides theoretical guidance and technical support for the upgrading and transformation of the commercial cryptography protection technology system in the power industry.

Design of Information Encryption Transmission Method for Power System Communication Network Based on Quantum Secure Communication Technology

Weilun Lao, Ken Chen

This paper proposes an information encryption transmission method for power system communication network based on quantum security communication technology, which can effectively encrypt the information in power system and ensure the security of information transmission. Based on quantum secure communication technology, the communication network architecture of power system is constructed. Quantum-layer quantum key distribution Network (QKD) uses BB84 protocol to realize quantum information exchange and optical synchronization, provide quantum key to control layer, and encrypt network information of power system. The control layer is responsible for monitoring QKD status, reasonably managing keys, and issuing communication commands to the communication layer. The communication layer switch encrypts and transmits the power system communication network data generated by the application layer through the minimum attenuation routing algorithm according to the controller instruction. Experiments show that this method can realize the information encryption of power system communication network, and the quantum key encryption function, key source exchange function and the number of encryption services meet the requirements. The application of this method can improve the throughput and communication connectivity of power system communication network.
