Abstract
The present invention relates to a dynamic security method and system based on multi-fusion linkage response. In the method, a site control device conducts active response and passive response through identity authentication and key management to give an alarm for abnormal behaviors. The system comprises an access authentication active response module, an access control active response module, an access control passive response module, an abnormal pretending passive response module, a key vulnerability passive response module and an abnormal state passive response mechanism module. On the basis of ensuring validity and feasibility for the security of a terminal device, the present invention can build a secure and trusted industrial control system operating environment.
