This paper provides an introduction and overview of power system real-time data encryption under network environment, describes the encryption requirements of power system real-time data communication, and briefly introduces a new type of a security-enhanced power system data encryption scheme. The QKD-based encryptions can delivering end-to-end network security via high-speed quantum key distribution, and against sophisticated eavesdropping attacks. QKD will be a most promising way of real-time data encryption in power system in the future.

Electric power information system is related with the safe operation of power grid. To ensure the data of electric power information will not be eavesdropped or deciphered, we need a strict way of encryption. With the improvement of computing capacity, traditional encryption algorithms are at high risk of crack. Quantum communication technology is an absolute security encryption mode, which can significantly improve the safety of electric power information system. For the particularity of electric power production and management data by analysing the principle of quantum communication technology, we have put forward implementation plan of electric power information system data encryption scheme and quantum communication network.

Currently, data security is one of the most concerning research topics. The traditional RSA encryption system has become vulnerable to quantum algorithms such as Grover and Shor, leading to the development of new security systems for the quantum. As a result, quantum cryptography is gaining importance as a key element of future communication security. This study focuses on quantum key distribution protocols for data quantum encryption, aiming to achieve quantum robustness in all stages of quantum cryptography communication processes. Quantum cryptography communication requires robust quantum encryption not only between end-nodes but also between all components. Therefore, this study demonstrates the process of end-to-end data quantum encryption and proves the overall quantum robustness in this process.
