摘　　要：无线传感器网络中,很多女巫攻击检测方法仅通过分析邻近节点来验证节点身份。针对该问题,提出一种结合消息验证和传递MAD(Message Authentication&Delivery)算法的女巫攻击检测方法。在数据传输过程中,通过节点位置验证方法比较当前中间节点信息与路由表,更新节点条目并验证。完成验证之后,收集节点的ID、时间戳和当前位置信息,并将这些信息与节点注册时的初始信息进行比较。而MAD作为一个预防措施,使每个节点通过传递认证消息进行通信。仿真实验结果表明:提出的方法在数据包传输、吞吐量和恶意节点检测率等方面表现优秀,添加MAD效果明显,可以有效抵御单播和多播中的女巫攻击。In wireless sensor networks,many Sybil detecting methods only verify the identification of the nodes by analyzing neighboring nodes.To solve this problem,this paper proposed a detection method of witch attack combined with message authentication and deliver(MAD)algorithm.In the process of data transmission,the node location verification method was used to compare the current intermediate node information and routing table,update the node entry and verify.After verification was completed,the node s ID,timestamp,and current location information were collected and compared with the initial information at node registration.As a precautionary measure,MAD enabled each node to communicate by passing authentication messages.Simulation results showed that the proposed method performs well in data packet transmission,throughput and detection rate of malicious nodes.The addition of MAD had obvious effect,which could effectively resist the Sybil attack in unicast and multicast.
