摘要: 由于无线传感器网络(WSN)具有资源有限、节点脆弱等特点,使得WSN中的节点易受DoS攻击。文章分析了现有方案的存储量和计算量等问题,并指出其存在的缺陷,在此基础上,提出了一种基于三层单向Hash链(TL-OHC)的抵御PDoS攻击的方案。该方案有效地减少了基站的负荷,并且缩短了中间节点的计算时间和计算量。

Abstract: Because of the restricted resources and fragile nodes in Wireless Sensor Network(WSN),it is easy to be attacked by DoS attacks in WSN.This paper analyzes storage and computational cost in some methods.It points out the limitations in them and presents a new scheme using a Three-Level One way Hash Chain(TL-OHC),which reduces the burden bear by the base station and cut the computational time and cost in intermediate nodes.

Key words: security, Wireless Sensor Networks(WSN), denial of services attacks, Three-Level One way Hash Chain(TL-OHC)
