无线传感器网络中基于序列的密钥管理方案

Sequence-based Key Management Scheme of Wireless Sensor Networks

针对目前的密钥管理方案过于强调安全性而忽视能耗方面的问题,提出了一种基于序列的轻量级动态密钥管理(SLDKM)方案。SLDKM方案将每个传感节点预存的递推公式和动态变化的初值结合起来构建一组序列密钥,用于和邻居节点建立安全通信。仿真结果表明:所提出的SLDKM方案在降低了网络通信开销的同时,可以有效地提高网络的安全连通率,并增强节点的抗捕获能力。

Because the current key management scheme didn’t achieve the balance between energy consumption and security requirement,a sequence-based lightweight dynamic key management(SLDKM)scheme for wireless sensor network was proposed.In the scheme,the pre-distributed recursive function was combined with the dynamical initial value to construct a set of sequence keys for secure communication with the neighbor nodes.Simulation results show that the proposed scheme decreases the network communication overhead,and improve the security connectivity and the ability of resilience to the attacks.
