Research on the application of data fusion technology in the security of wireless sensor networks

Abstract

The problems and influencing factors of data security in wireless sensor networks are analysed. In order to improve the security of network data, the data fusion technology is reasonably applied to wireless sensor networks. Shortcomings of the current data fusion technology are studied, and based on characteristics of the homomorphic encryption data fusion technology, we improve defects of the homomorphic encryption data fusion technology. On the base of the elliptic curve cryptography homomorphic encryption, the sub-domain data security protection fusion algorithm is put forward. A new model of networks is constructed, and perceived nodes of wireless sensor networks in different regions are processed. Through experimental simulation and comparison, the new fusion algorithm of data security can effectively heighten the robustness of the network, and reduce energy loss and communication loads of networks. The new fusion algorithm improves performances of wireless sensor networks.
