Abstract:

In order to accurately detect the location of attacking nodes and implement targeted capture processing on them, an IoT node capture attack detection system based on embedded and ASG technology is designed. Through the data message capture module, data message analysis module, and message processing module, the execution process from node definition to node real-time processing is optimized, and the IoT node object is debugged according to the operation of the attack detection and location module to realize the hardware design of the detection system. Use the encryption, decryption and key management results of the node information captured by the IoT host to determine the node authentication process and complete the design of the embedded IoT defense mechanism. According to the ASG technology implementation standard, collect worm samples, judge the feasibility of feature generation and distribution processing instructions, complete the formulation of key detection instructions, and implement the design of the Internet of Things node capture attack detection system based on embedded and ASG technology. The experimental results show that the average detection accuracy of the designed system for the location information of aggressive nodes is as high as 96.7%, which can accurately detect the location of aggressive nodes and enhance the directional capture and processing ability of aggressive information samples.
