Research on the wireless protocol security detection model of Internet of Things terminal transmission in new power system to improve the effectiveness of protocol security detection.By analyzing the new power system based on Internet of Things,the common wireless protocol attack types of Internet of Things terminal transmission are determined.Based on the identified attack types,a wireless protocol security detection model for Internet of Things terminals in the new power system is established.In this model,the transmission wireless protocol analyzer analyzes the transmission wireless protocol of Internet of Things terminal through Sketch method.Feature extraction algorithm selector,according to the protocol analysis results,choose principal component analysis or independent component analysis,extract transmission wireless protocol intrusion characteristics.The security detection engine uses the least square support vector machine and the extracted intrusion features to output the attack type of the transmission wire-less protocol and complete the detection result of the transmission wireless protocol security.Experiments show that this model can effectively extract the wireless protocol intrusion characteristics of network terminal transmission and implement protocol security de-tection.For different types of Internet of Things terminal,the Kappa coefficient of security detection of this model is high,that is,the security detection accuracy is high.
