Research on Terminal Credibility with Power Internet of Things Based on Behavior Measurement Mechanism

Based on the analysis of the security requirements of power internet of things and the idea of security solution provided by trusted computing, this paper studied the power Internet of things information security interaction model and key technologies to realize the information security interaction of power internet of things, and proposed a real-time evaluation model of terminal entities based on global trusted. Punishment factor and time factor were introduced to upgrade the evaluation method from single evaluation to global evaluation. Taking the power distribution system as an example, the information security intersection model of power internet of things based on behavioral trusted measurement mechanism was simulated. The simulation results showed that the model had continuous trusted measurement ability in dynamic uncertain network environment, and could make trustworthiness decision in real time and accurately. It is more practical and laid a good foundation for the research of trustworthiness connection, trustworthiness management and trustworthiness decision-making based on trusted measurement.
