摘　　要：针对异构传感网中传统的安全协议存在能量不均衡以及缺少对单向链路的考虑等问题,该文设计了一种能量均衡的新型密钥管理协议。在EG方案的基础上,周期性建立重聚簇和设置单项链路密钥建立机制。实验证明,所提协议能够在保持异构传感网高能节点优势的同时,实现高能节点能量退化后的全网能量均衡。提高了特殊路径的网络连通概率,从而延长了网络寿命,保证了网络节点工作的安全性。Aiming at the problems of traditional secure protocols for heterogeneous sensor network such as nonbalanced energy and lack of consideration for one-way link,a new energy balance key management protocol is proposed.Reunited clusters are made periodically and a one-way link eatablish mechanism is buit based on EG scheme.Experimental results demonstrate that the proposed protocol can maintain the advantages of the high-energy nodes in the heterogeneous sensor network,achieve the energy balance of the whole network after the energy degradation of the high-energy nodes.The connectivity probabilities of the special paths in the network are improved,the lifetime is prolonged and the security of the network nodes is ensured.
