摘要： 提出一种基于簇的平面Merkle哈希树的Sybil攻击防御机制。将网络分成簇，单个簇内的节点维护一棵Merkle哈希树，利用Merkle哈希树生成密钥。理论分析与模拟实验证明，该机制具有较高的安全连通性和较低的能耗，有较长的网络生命周期和较短的认证时延。

Abstract: This paper proposes a Cluster-based Merkle hash tree Defending Mechanism(CMDM) for Sybil attacks, aiming to the limited computation and memory in Wireless Sensor Network(WSN). CMDM divides the network into clusters, in which all the nodes sustain a Merkle hash tree that is used to build keys. Compared with the existed solutions, CMDM has a higher secure connectivity and lower energy consumption. Theoretical analysis and simulation results show that CMDM increases the network lifetime and has smaller latency than existed scheme.
