网络入侵中的异常信号抗干扰检测系统的设计与实现
Design and implementation of anti-jamming detection system against abnormal signal in network intrusion
摘要
Abstract
Since the network intrusion types are varied,which may lead to a low detection accuracy and the stability of antijamming detection system against abnormal signal in network intrusion,a high performance interference detection system against abnormal signal in network intrusion is designed.The system consists of incentive end,detecting end and processing end.The incentive end converts the signal generated by the network intrusion into sine wave signal,and transmits the sine wave signal to the detecting end after amplification.The incentive end generates excitation signal and standard signal at the same time to invoke the detecting end to detect the abnormal signal and deal with the initialization of the processing end.The detecting end receives the excitation signal and the sine wave signal through the sensor,taking the sensor coil output voltage as input of abnormal signal detection to realize the anti-jamming detection of abnormal signal.With processing chip S3C2440a,the processing end filters,rectifies and displays the network intrusion abnormal signals detected by detecting end.The experimental analysis result shows that the designed system has high detection accuracy and stability.关键词
