Research On Data Fusion Method For Privacy Protection In Energy Internet

With the development of the energy Internet,the complex networks such as the intelligent transportation network and the natural gas network and the power system control network are interconnected.In this large network,information flow,energy flow and control flow between the conversion,produced a large amount of data information.In addition,in the data collection and monitoring in the network,multiple sensors monitored the same measured object and collected a large amount of redundant data.To get the information you need from these data,you have to do data fusion with them.At the same time,there are many security issues in the fusion of these data.In order to ensured the accuracy and confidentiality of the fusion result,the data fusion needed to be protected by privacy.In this background,this thesis analyzes the basic architecture of energy internet.In view of the redundancy and insecurity of data collection and monitoring data in the energy Internet,the necessity of encryption and security fusion is explained.The data fusion method for wireless sensor network in energy Internet is studied in this thesis.Two scenarios of wireless sensor network in the energy Internet are listed,which are the wireless sensor network in power system and the application of intelligent transportation system,and the wireless sensor network in these two scenarios for the necessity of the privacy of data fusion is illustrated.This thesis analyzes the data fusion method in wireless sensor network and studies the traditional data fusion method ICKPDA.ICKPDA algorithm of the third phase of gathered data fragmentation stage,in which only leaf nodes have data fragmentation but non-leaf nodes do not have data fragmentation.According to this problem,the IICKPDA-1 algorithm is designed in the case of multiple sensors gathering multiple monitoring parameters,which improve the precision of the data fusion in wireless sensor network and privacy protection.Selection of energy in the Internet application scenario for the power system,the model of wireless sensor network of energy on the Internet is established.For the problems that may arise when multiple wireless sensors collect the same monitoring parameters in the selected application scenario of IICKPDA-1,The algorithm of IICKPDA-2 is designed to improve the stability of data fusion.Since the algorithm of IICKPDA-1 and the algorithm of IICKPDA-2 are basically consistent with accuracy,privacy protection,data traffic and data integrity,the simulation software was used to simulate the algorithm of IICKPDA-2.The experiment proves that the accuracy of IICKPDA-2 is better than that algorithms of ICKPDA and ESPART.The theoretical analysis of the algorithm of IICKPDA-2 from three aspects of privacy protection,data traffic and data integrity proves that the algorithm of IICKPDA-2 is better than the algorithms of ICKPDA and IPDA.
