摘要

提出了一种新的防御思路:通过使复制节点无法与邻居节点建立成对密钥的方式

来达到消除复制节点攻击威胁的目的

由此设计了一种基于多项式的成对密钥分发方法LTB(location and time binding)。LTB把每个节点的密钥信息与其部署位置和时间信息绑定起来

使每个节点只能在其部署位置与邻居节点建立成对密钥。由于复制节点的部署位置不同于原捕获节点

因此LTB能够有效阻止其与邻居节点建立成对密钥。LTB相比现有各种周期性复制节点检测机制的优势是它彻底消除了复制节点攻击隐患而且协议开销更低

通信开销从O(pn3/2)下降到O(n)

其中

p是检测周期数

n是网络节点个数。

Abstract

A novel pairwise key predistribution approach called LTB （location and time binding） was proposed

in which the key material of each node were bounded with its original deployment location and time so that each node could establish pairwise keys with its neighbors only at its original deployment location. Since replicas were deployed at different locations other than the original

they could not be accepted by their neighbors. LTB eliminates node replication threats completely while its communications overhead is much lower than that of periodical detection approaches with O（n） against O（pn3/2）

in which p is the number of detection periods and n is the number of nodes in the network.
