Edge device function protocol backdoor detection and malicious sample library architecture model

The invention provides a technical method of edge device function protocol backdoor detection and malicious sample library architecture model aiming at security protection of industrial internet and internet of things edge devices and introduction of a decentration idea. According to the method, an OPC (OLE for Process Control) communication service component for industrial process control is used for constructing edge device data acquisition controllers with different protocol standards to serve as a unified internet-of-things model of the industrial internet, and a plurality of security and credibility authentication components are implanted into the model. The component can capture abnormal instructions, abnormal protocols, abnormal data access, abnormal data streams and the like generated by edge device function protocol backdoor software, and meanwhile, on the basis of classification analysis and screening authentication, global synchronous release is performed through a multi-stage malicious sample libr
