Secure Multidimensional Data Aggregation with Secret Sharing in Wireless Sensor Networks
Secure data aggregation in wireless sensor networks(WSNs)is used to enhance the data privacy and reduce energy consump-tion,which extends the life of the whole network.To solve the problems of low data transmission security and high data transmission en-ergy consumption in multidimensional WSNs,a multidimensional data aggregation scheme with thresholds changeable secret sharing method(TCSSMDA)is proposed.In the proposed scheme,the cluster head selection of the network is determined according to the remai-ning energy of the nearby nodes and the distance to the base station.Moreover,to reduce the energy consumption of the multidimension-al data transmission,the preset values are used to optimize the data sending mechanism of the multi-dimensional sensors in the system.Finally,to enhance the data security in the sensors,a lightweight and efficient data encryption method is designed based on secret sha-ring with variable threshold.Security analysis and simulation result show that the proposed scheme can be performed with high efficiency in reducing the packet size and node communication cost,and improving the data security and the network lifetime.
