摘　　要：由于无线传感器网络能源受限、拓扑易变化等特性,需要解决其密钥管理机制涉及到的机密性、完整性、源端认证和无充足空间存储大量密钥信息等问题。针对当前研究工作的一些局限,提出了一种基于逻辑网格的无线传感器网络密钥分配方案,基于层簇式的网络拓扑,描述了系数矩阵求解、密钥设定和具体实现的流程。最后通过与多种现存方法(例如SPIN协议和逻辑密钥树方案)的仿真实验比较,验证了该方案在安全性、存储性和节能性方面的优势。Owed to the obvious characters of energy-constraint and dynamic topology, issues including confidentiality, integrality, authentication and no sufficient memory for abundance of key information, needed to be effectively solved in key management technique, especially in wireless sensor networks （abbreviation for WSN） applications. Aimed at some limitations like these on current research work, a key distribution scheme based on logic grid of WSN was proposed, which used the layer-cluster topologic structure. The complete process was described, involving resolution of coefficient matrix, keys＇ initialization and specific realization. Compared with some other schemes, such as SPIN protocol and logic key tree methods, simulation results show its advantages on security, memory performance and energy- consumption, etc..
