Enhancing the Information Security of Distribution Automation System in Low Voltage Area Using Quantum Cryptography

Abstract

Power transmission and utilization systems are an integral part of the electrical grid's link to the end user. Ensuring the safe and sound transfer of data across all systems is closely tied to safeguarding personal information. This work presents a quantum cryptography solution that can improve the data safety of distribution automation systems in the low-voltage unit region. All three levels of the system—base station, access, and terminal—were considered throughout its design. The information that was delivered across the quantum key distribution (QKD) system was encrypted using a quantum key that was created by the key production modules on both ends of the transmission. This study accomplished the goal of facilitating the flexible and cost-effective transfer of the terminal-end quantum key in the context of QKD.
