Assuring Cyber Security in Smart Grid Networks by Fuzzy-logic based Trust Management Model

摘要

Smart Grid constitutes a network many lightweight devices. Through this network, the devices can exchange information. Compromisation of these devices can breach the security of the network. In this paper, we have proposed a trust management model based on fuzzy system to address the above-mentioned issue. we have successfully enhanced security of the smart online grid connected network system and eliminated compromised device. The model has been simulated in Xfuzzy-3.5. Simulation results depict that to be a trustworthy device, each device requires to maintain its trustworthiness behavior above the threshold, otherwise it will be treated as a malicious device. Simulation results show the maximum correctness and it is competent with the objective of this paper. Finally, the simulation results enhance the security in Smart Grid network through Trust management model which is satisfactory proven.
