Design of remote terminal control system of 5G mobile communication network based on state secret algorithm
Abstract：Communication data encryption errors are the main reason why mobile network hosts cannot reasonably control information transmission behavior. In response to the above issues, a 5G mobile communication network remote terminal control system based on the national security algorithm is designed. Based on the 5G mobile communication unit structure connection model, combined with the CAN bus arbitration structure of the communication network and the remote mobile control terminal, the hardware module design is completed. According to the national security algorithm model, generate the necessary key text, and solve the specific hash function by defining a digital signature. On this basis, analyze the communication data transmission behavior and complete the 5G mobile communication network data encryption based on the national security algorithm. In the voting surface of mobile communication networks, implement the conversion of 5G protocol and remote terminal protocol, and develop specific communication control task division standards to achieve the execution of control programs within network remote terminals, and complete the design of a 5G mobile communication network remote terminal control system based on national security algorithm. The experimental results show that the designed system can control the error between the length of the communication data encoding code source and the length of the decoding code source within the allowable error rate range of 0-0.15bit, effectively reducing the problem of mobile network hosts being unable to reasonably control information transmission behavior due to incorrect encryption of communication data.
