The use of quantum true random numbers and one encryption at a time method to ensure the security of quantum-secret communication under realistic conditions. Use the quantum true random number generator to generate the determined true random number key file, and generate the joint key file through the bitwise XOR operation. After the user group and the corresponding server pass the identity authentication, they can obtain the key from the key distribution center. Using the communication method of trusted repeater, the repeater terminal hold the keys of all users, and each user only needs to store his own key. This method solves the problem that users need to store a large number of keys during multi-party communication, and uses the stored quantum key resources to more easily and quickly establish secure communication networks for exclusive individuals, organizations, and various industries.

Based on quantum true random numbers, combined with one-time pad encryption algorithm, a secret security control system based on UAV IoT system is realized. The keys of the two sides of the drone and its remote control are fully synchronized to ensure the encrypted and safe flight of the drone. Even in the case of missing instructions, it can still maintain normal encrypted communication; The encryption and decryption operations are all bit-wise operations, which allows the processor to execute quickly and transmit commands in real time; The key supplement and update method is simple and efficient; The UAV encryption control solution can be extended to other devices in the Internet of Things, including monitoring systems, high-speed rail operation control systems, smart grids, etc. This solution can achieve safe and confidential control between the Internet of Things remote wireless communication devices.
