Abstract 
With the rapid development of information technology, the security of network communication has become increasingly prominent, and the traditional encryption methods have been difficult to meet the growing security needs. Under this background, the secure communication protocol based on quantum encryption comes into being, which provides a new and highly secure information transmission method for network communication. This paper aims to discuss the design and application of secure communication protocol based on quantum encryption, analyze its advantages and characteristics in ensuring communication security, and look forward to its future development prospects. Quantum encryption technology is a kind of encryption method based on the principle of quantum mechanics. It makes use of the properties of quantum state such as non-cloning, uncertainty principle and entanglement to realize the function of non-replicability of information and real-time detection and eavesdropping. By combining these characteristics, a communication protocol with high security is designed, which can realize fast transmission and efficient processing of information while ensuring communication security. In the design of secure communication protocol based on quantum encryption, it mainly includes two aspects: key distribution protocol and message transfer protocol. Key distribution protocol is the cornerstone of secure communication. It uses the non-clonability of quantum state and the singularity of quantum measurement to realize key distribution and verification. A common key distribution protocol is the BB84 protocol, which uses photons of four different polarization states to represent the value of bits, and verifies and screens valid key bits by quantum measurement. After the key distribution is complete, a message transfer protocol needs to be designed to realize the transmission of encrypted information. Common quantum messaging protocols include E91 protocol, which uses the properties of quantum entanglement to achieve secure transmission of information. The secure communication protocol based on quantum encryption has shown its unique advantages in practical applications. In the banking security communication system, quantum encryption technology can ensure that the important information of the bank is not stolen in the transmission process, effectively improving the security of the banking system. In the secure communication system of government agencies, quantum encryption technology can prevent external forces from prying into sensitive information and ensure national security. In addition, in the military communication security system, quantum encryption technology can also ensure the safe transmission of information and avoid security problems caused by information disclosure.
