Research Of CPSnet Security Technology In Smart Grid

Recently, the development of the networks has been shown in two sides. The first one is the relation between physical networks and communication networks. The second one is the relation between communication networks and social networks. So we can infer that there is a converged network that is fused by social networks, communication networks and physic networks.The converged network has improved the efficiency of industry productivity, improved the quality of people’s lives. However, the complex connection between those three networks also created security issues. The attackers will attack communication networks through social networks and eventyally destroy physical networks.Aiming at this problem, we start by relations between networks, analyze the converged networks in smart grid by modeling and simulating, find measures of improving the security of the networks by locating several key roles in the networks, and we list our main work as follows:Firstly, we model the social networks. We summarize several actors in attacker organization and protection organization and the relations between them by reading material of the cases of network attack. We associate the actors in protection organization with inner communication network by analyzing the actors’ duty and authority. We store and present the actors and relations by matrix.We propose several measures to improve the security of the networks and reduce the possibility of attackers intruding communication networks through society networks by matrix operations.We locate several key roles in the security of smart grid. We propose several measures to improve the security of the networks in smart grid by simulating cascading failures in smart grid.At last, we design and implement a simulating platform based on the above research. The platform is used to calculating the relations between society networks and communication networks, and fulfills the simulation of cascading failures in smart grid.
