分析了无线传感器网络中严格的资源限制和自组织特点并据此提出密钥管理协议所需满足的要求。在结合当前最新成果并对典型的密钥管理方案进行系统论述的基础上,对其利弊以及适应性问题进行了较为全面的分析,且于最后提出一些颇具价值的研究方向。
The tenet of key distribution is detailedly analysed in wireless sensor networks with reference to their resource constraints and self-organization property.Based on systematic characterization of recent typical key management schemes,their gains and losses as well as their applicability are addressed.Some promising search orientations are also presented in conclusion
