分簇传感器网络中对密钥管理方案

本文提出一种分簇传感器网络中的基于双变量多项式的对密钥建立方案，无需可信第三方存在，整个网络被划分戍若干个簇，根据节点的可信度选举出簇头，能够保证任意两个簇头节点都可以建立对密钥，任意两个簇内节点也可以建立对密钥。

Pair-Wise Key Management Scheme in Clustered Sensor Networks

In this paper, we propose a hierarchical distributed pair wise key establishment scheme based on the concept of bi-variant polynomials. In our scheme, it needn't a trusted server, the network is divided into clusters based on trust evaluation (given by neighbors) with one special cluster head node. And these cluster head nodes (CHs) in the network can establish pair wise key with each other just by knowing their corresponding IDs without any communication. Every two nodes in the same cluster can also establ...
