摘　　要：在无线传感器网络中使用hash算法取代传统的公钥加密算法(PKC),提出了基于能量层和位置关系分簇算法的公钥认证策略(SPABEP),该策略可以有效地减少节点内存空间的消耗.在对SPABEP进行改进的基础上,又提出了基于部署信息的簇结构公钥认证策略(SPABDK),SPABDK更好地优化了节点内存空间消耗与通信负载的关系.仿真结果表明所提出的基于簇结构的公钥认证策略比传统的公钥认证策略具有更好的节能性能.This paper replaces Public Key Cryptography（PKC）with a hash algorithm, and presents a strategy for public key authentication based on energy band and position clustering algorithm （SPABEP） in wireless sensor networks, which could effectively reduce memory consumption. Improving SPABEP, this paper also presents a strategy for public key authentication based on deployment knowledge with cluster structure （SPABDK） , which could optimize the relationship between memory consumption and communication load. The simulation indicates that the above strategies have a better performance than the traditional public key authentication strategy in energy saving.
