基于完全层次树的无线传感器网络密钥共享方案研究

Secrets Shared Scheme for Wireless Sensor Networks Based on Complementary Tree Protocol

无线传感器网络由于其自身的特性,如计算资源、能量、存储资源以及带宽的局限性从而面临巨大的安全问题,较普通网络更易受到外界的攻击。研究了一种在无线传感器网络中使用的完全层次树的节点密钥共享方案,该方案使任意两个节点之间共享若干密钥。理论和应用分析显示所提出的方案具有有效性和安全性的特点。同时,通过相关方案比较表明该方案较其它方案更适合无线传感器网络,可以有效的抵御一类Rushing引起的网络DoS攻击。

Securities of wireless sensor networks have received considerable attention recently. Because of limitations of power, computation capability, storage resources and networks bandwidth, wireless sensor networks are easier to be attacked by adversaries than traditional wire networks. The paper proposes a secret shared scheme for wireless sensor networks based on complementary tree, The scheme provides a way with which any two nodes in wireless sensor networks can share some keys. Analysis shows that the scheme is effieient and safe for wireless sensor network. It can be used to defend against the DoS attack caused by Rushing.
