Multiorder Fusion Data Privacy-Preserving Scheme for Wireless Sensor Networks

Privacy-preserving in wireless sensor networks is one of the key problems to be solved in practical applications. it is of great significance to solve the problem of data privacy protection for large-scale applications of wireless sensor networks. the characteristics of wireless sensor networks make data privacy protection technology face serious challenges. at present,the technology of data privacy protection in wireless sensor networks has become a hot research topic,mainly for data aggregation,data query,and access control of data privacy protection. in this paper,multiorder fusion data privacy-preserving scheme (mofdap) is proposed. random interference code,random decomposition of function library,and cryptographic vector are introduced for our proposed scheme. in multiple stages and multiple aspects,the difficulty of cracking and crack costs are increased. the simulation results demonstrate that,compared with the typical slice-mix-aggregate (smart) algorithm,the algorithm proposed in this paper has a better data privacy-preserving ability when the traffic load is not very heavy. © 2017 mingshan xie et al.
