一种安全的无线传感器网络结构设计方案

摘要

This paper propose that a secure data communication architecture for the three-tiered wireless sensor networks that continues to operate correctly in a hostile medium is proposed.Due to the importance of secure in WASNs, a management scheme is proposed that supports three types of keys for the whole network.Considering the energy and hardware constraints of the sensor nodes, the low complex data confidential and authentication algorithms are proposed.The simulation shows that it has good energy saving and safety.%文章提出一种三层无线传感网的安全数据通讯结构,该结构使网络能在敌对的环境中正确地工作.为了确保网络的安全性,提出一个在整个网络中支持三种类型密钥的管理方案;考虑到能量和传感器节点硬件的限制,提出低复杂度的数据加密和证明法则.通过仿真,证明该方案具有良好的节能性和安全性.
