摘要
无线传感器网络在部署初始阶段,由于未被恶意者察觉,或者破解存在难度,节点通常能够在一定时间内具有抵抗劫持的能力.基于此分析提出一种适合于静态网络的基于一次性预共享密钥的安全管理方案SMOPK,方案在无线传感器网络部署的初始阶段利用一次性预共享密钥进行密钥协商等,从而在相邻节点间建立保密的安全连接,建立与实际拓扑一致的安全拓扑.分析表明SMOPK方案具有开销小、安全性强的特点,适合于静态无线传感器网络的安全要求.
In the initial deploying stage of wireless sensor networks, because of not being detected or hard to break by attackers, every node has ability to resist being hijacked. Based on onetime preshared key, a security management scheme SMOPK, suitable for static network, was introduced. The scheme used onetime pre-shared key to perform consultation of secret key, and therefore realizing secured links between neighboring nodes and building up a secured topology which is consistent with the actual wireless topology. Analysis showed that the scheme had strong security features with low cost.
