基于秘密分享的无线传感器网络多维数据安全聚合方案

Secure Multidimensional Data Aggregation with Secret Sharing in Wireless Sensor Networks

无线传感器网络中的安全数据聚合方案旨在保护数据隐私、降低系统能耗,从而延长网络的生命周期。针对目前多维无线传感器网络中数据传输安全性不高、数据传输中的能量消耗过大等问题,提出一种基于阈值可变秘密分享的多维数据聚合方案(TCSSMDA)。首先,在本方案中,网络簇头的选择主要是依据网络节点的剩余能量以及其与基站的距离。同时,为了降低多维数据传输的能量消耗,使用预设值对多维传感器发送数据机制进行优化。最后,为了保证传感器的数据安全,使用设计了一种轻量级、高效通信的信息加密方式。安全性分析与模拟结果表明,所提出的方案在降低数据包大小、节点通信成本以及提升网络数据安全性和生存时间方面都表现出了较好的性能。

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.
