This paper proposes a distribution network application scheme based on quantum secure communication and 5G hard slicing private network. The method can calculate the quantum key update frequency and distribution strategy of each power business by itself. The system performs the key self-evolution of the synchronization between the sender and the receiver by transmitting the random quantity of short length generated in the communication in the quantum channel. It replaces the traditional update method where a new full key must be sent and received after each update must be renegotiated. Finally, this paper proposes the key reading mode between the service terminal and the quantum key mobile storage device, the interface protocol between the service terminal device and the quantum key mobile storage device, and the key management method suitable for the power distribution service terminal. The experimental results show that the described method can realize the automation and intelligence of the optimal distribution of quantum keys for accurate data protection of various power services. This method can construct a precise and secure data protection mechanism based on quantum keys.

The evolution from 5G to 6G wireless networks is driving a fundamental transformation in encryption technologies. While 5G networks primarily rely on advanced classical cryptography, including AES, ECC, and RSA, emerging applications such as IoT, e-healthcare, and ultra-reliable low-latency communications demand lightweight, hybrid, and context-aware security schemes. The advent of quantum computing poses significant threats to classical cryptosystems, motivating the integration of quantum-resistant security techniques, including post-quantum cryptography (PQC), quantum key distribution (QKD), and physical layer security (PLS) in 6G networks. This review synthesizes recent research on classical, hybrid, and quantum-resistant security techniques, highlighting the shift toward multi-layered and adaptive security frameworks. A comparative analysis of PLS in 5G and 6G illustrates its transition from a complementary role to a core security mechanism, especially in ultra-low-latency, massive connectivity, and heterogeneous environments. Finally, open research questions and standardization challenges are discussed, emphasizing the need for scalable, energy-efficient, and interoperable security solutions for next-generation wireless networks.
