实现位置及时间绑定的密钥分发——防御传感器网络节点复制攻击的新方法
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
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.
