基于虹膜特征密钥的无线传感器网络安全数据融合

摘要

本文针对无线传感器网络中的数据融合操作面临严重的安全隐患,提出了一种基于虹膜特征密钥的数据融合加密方案,该方案不仅解决了在数据融合过程中密钥记忆和存储难的问题,而且也避免了中间节点攻击数据融合结果的问题.通过抗攻击能力仿真实验分析,该方案相比于传统的数据融合方案较为合理,减少了节点能量消耗,延长了网络生存周期.%Aiming at the serious hidden danger of data fusion in wireless sensor networks,this paper proposes a data fusion and encryption scheme based on iris signature key.This scheme does not only solve the problem of key memory and storage during data fusion,it also avoids the attack of the intermediate nodes on the data fusion result.Simulation results show that the scheme is more reasonable than the traditional data fusion scheme,which reduces the node energy consumption and prolongs the network life cycle.
