Trusted Computing-based Network Security Data Collection for Substation Monitoring Systems
The network security data of the substation monitoring system is sent to the network security monitoring device through the probe module,but there are certain risks to the security and operation credibility of the probe,and the legality of communication with the network security monitoring device.A network security data collection method for substation monitoring system based on trusted computing is proposed.First a trusted computing operating environment is deployed in the monitoring system to ensure the security and trustworthiness of the monitoring system and the probe,forming an op-erating environment with trusted computing platform,trusted application behavior,and trusted network communication.Second effective authentication of the identities of both communication parties is carried out to ensure the legality of com-munication between the probe and the network security monitoring devices based on digital certificates and national securi-ty algorithms.Finally the integrity of the collected data is verified to improve data collection reliability and accuracy.
