无线传感器网络中对密钥管理评估指标研究

该文研究了无线传感器网络中的对密钥管理的评估指标。鉴于无线传感器网络与传统网络的不同，首先介绍了无线传感器网络存在的限制，这些限制将影响网络巾的对密钥管理方法以及安全技术；接下米针对无线传感器网络特殊性及其自身的特点总结提出了一套对无线传感器网络中对密钥管理方案的评估指标；接着从当前无线传感器网络对密钥管理研究现状出发，按照该文提出的评估指标对现有的两种类型的对密钥管理方案进行分析比较。根据这一评估指标的分析结果可以针对不同应用环境选取合适的对密钥管理方案。

Pair-wise Key Management in Wireless Sensor Network

In this paper, the evaluation metrics of the pair-wise key management in wireless sensor network is discussed. Firstly, because of the difference between the traditional network and wireless sensor network, the constraints in wireless sensor network, which influence the design of key management schemes in that environment are introduced. Then the evaluation metrics about pair-wise key management schemes is presented. Finally, the kinds of pair-wise key management schemes are analyzed and compared according to the evaluation metrics proposed in this paper. By these analysis, a proper pair-wise key management scheme for different situation can be chosen.
