Design of Railway Communication Network Security Encryption Control System Based on Narrowband IoT
Railway communication network is prone to network attacks during data transmission,which reduces the security of the network.To address this issue,a railway communication network security encryption control system based on the narrowband Inter-net of Things was designed.Using STM32F103 as a narrowband IoT control terminal chip,it is used to collect,process,and analyze the data.Through the control terminal and human-machine interface,USART is used to download and debug the computer,and de-sign the interface data transmission circuit.The input current signal and voltage signal are switched by using a dial switch circuit,and the output voltage is corrected by adjusting the resistance to achieve efficient data transmission.The narrowband IoT encryption tech-nology is applied to ensure that each sub organization has a unique attribute key.Combined with AES encryption algorithm,the data is encrypted into the ciphertext.Through inverse transformation and decryption processing,noise phase is obtained to avoid disorder-ed ciphertext affecting the sorting of sub ciphertext,and achieve the communication network security encryption control.Testing re-sults show that the maximum channel error rate of the designed system does not exceed 30％,and the maximum network throughput is 260 bit/s,which has efficient encryption control capability.
