Abstract:

In order to control the relative delay between plaintext encryption duration and ciphertext response duration, and realize the security encryption of wireless network for communication data, a security encryption control system for wireless communication network based on Modbus/TCP is designed. Match the real-time connection relationship between the PowerPC embedded architecture and the reset communication control circuit, determine the contribution value of the host and client to the communication network with the help of the microprocessor sub module, and then integrate the communication data text stored in the switching area according to the Modbus/TCP protocol connection standard to complete the hardware design of the wireless communication network security encryption control system. According to the basic protocol elements, the transmission identity of the data to be encrypted is authenticated to define the Modbus/TCP trusted protocol. Using the credibility conditions in the protocol file, set the key template, determine the total capacity expansion of data information samples by transplanting and processing the communication text, complete the design of the security encryption interface, and combine relevant application components to achieve the design of the security encryption control system of the wireless communication network based on Modbus/TCP. The experimental results show that the relative delay between plaintext encryption duration and ciphertext response duration of the designed system is always 0.1 ms, which can effectively realize the security encryption of communication data in wireless networks.
