无线传感器网络中密钥管理方案的综合评估

针对如何选取有效密钥管理方案是实现无线传感器网络安全的关键问题,提出一种密钥管理方案的综合评估方法.该方法利用总结出的密钥管理方案的评估指标,构造了综合评估结构模型.结合模糊方法和层次分析法,把评估密钥管理方案性能的主观因素限制在很小的范围内,有效地提高评估结果的准确度和可信度,可根据需要快速选择合适的密钥管理方案.经实验验证该方法是有效的.

Comprehensive Evaluation of Key Management Scheme in Wireless Sensor Networks

To the crucial point of how choose effective key management scheme to realize security of wireless sensor network, this paper presents a comprehensive evaluation approach on key management. This method constructs model of comprehensive evaluation with metrics worked out on key management. Combined with fuzzy method and hierarchical analysis method, the subjective factors on evaluation functions of key management scheme are reduced to minimum. The accuracy and believability of the evaluation results are effectively improved. It ensures to choose effective key management scheme according to the requirement. Finally, the effectiveness of this measurement is verified by an experiment.
