Research On The Security Of Smart Grid Data Storage Based On Cloud Computing

Smart Grid has become a hot topic discussed by the world since it was proposed. As the direction of future research and development of the power grid, its structure and scale are becoming increasingly complex and huge, and the data will show a massive growth. Cloud computing technology with distributed computing, high reliability, fault-tolerant and scalable features, can provide an effective solution to the problems encountered in the development of Smart Grid. Because of the special position in which the electric power system, how to protect the smart grid data is of great significance for the safe and stable operation of the data in Smart Grid is of great significance. So in this paper we mainly studies the security of the data stored in Smart Grid.In this paper we firstly discuss the research background and significance of the subject. Analyze the data characteristics of Smart Grid and some data security issues, and the current status of the research on the security and integrity of the data. In this paper we mainly completed the following works: first, the inadequacies of the common hybrid encryption algorithm were analyzed, and the improvement of hybrid encryption algorithm was realized. And experimental verification and analysis were carried out to show that the method can improve the security of the data. Second, by analyzing the existing methods of integrity verification, and combining with the characteristics of Smart Grid, the improvement of the integrity verification methods was completed. Experimental results show that the method can improve the accuracy and efficiency of the verification. Finally, the simulation experiment of Smart Grid was carried out, and improved methods were used. Through experiments we can proposed that the improved methods can improve the security of the data stored in Smart Grid.
