摘要 针对现有无线传感器网络密钥管理中计算量过大、存储空间过多和管理不够灵活的问题,在分簇结构无线传感器网络基础上,定义了数据在无线传感器网络中的通信格式以及在网络动态管理中所需的管理矩阵,混合了对称密钥管理策略中密钥产生的快捷性和公钥管理策略的安全性,实现了密钥的动态更新和网络的动态密钥管理。最后分析所提出的策略,对比现有成熟的密钥管理策略,证明了所提策略具有更好的特性。 According to the existing problems in current key management strategy of wireless sensor network——overwhelming computational complexity,multi-memory space and inflexible management.Based on the clustering wireless sensor networks,this paper defined the data format in the communication of the wireless sensor networks and management matrix in the network dynamic management,mixed the rapidness which was produced in the symmetric private key management strategy and security of public key management strategy,imp...
