| With the rapid development of economy and the usage of electricity power,power departments need to build a so-called Smart Grid with two-waycommunication system to realize real-time control and to locate errors. So thetopology of SG network has become the focus of many scientists and engineers.Besides, with people’s security awareness strengthening, and the special featuresof electricity power as a governmental strategic department, the function of thenetwork to ensure the security of the information also attracts the attention ofscholars. To study the topological structure and the secure algorithm aims toincrease throughput and security of data.This paper did research of the structures of SG network’s core network andaccess network and techniques within those structures to ensure security, andanalyzed their influence of the whole network. And it is proved reliable andefficient in theory and testified in computer simulation. The main results of thispaper are shown as followed:First, this paper proposed a novel structure of SG network to fulfill itsspecial requirement of security and the ability of data throughput. This structureuses wired communication in its core network and wireless one in its accessnetwork.Second, it proposed to adopt random linear network coding in the corenetwork to increase throughput to fulfill the requirement of real-time processinglarge quantity of data. Besides, it reconstructed network codes with securityalgorithm to secure the whole core network.Finally, it gave a typical system model based on the occasion where existsan eavesdropper. Also, it simplified the wireless channel model of the system,and used polar coding to insure reliability and security. Theoretically, this paperproved that the usages of polar coding fulfill the requirement of the network.Besides, with the computer simulation, experimentally proved the efficiency ofthis structure, and it set up an example of SG network for other scientists andengineers. |
