摘　　要：冒充性攻击伪装成合法的通信实体,向无线传感网络中的传感节点发送虚假的信息或命令,降低了网络信息数据推荐的效率,影响网络安全性。为此,研究了一种冒充性攻击下的无线传感信息数据安全推荐算法,以保证通信质量。计算冒充性攻击下的无线传感网络邻居节点的信任度,从中选取信任度取值比较高的节点组建备选推荐无线传感节点集合。对备选节点推荐集合展开数据去噪、冒充性攻击检测和重构处理,同时将用户自定义标签映射为标准标签,以此建立可躲避攻击节点模型。获取可躲避攻击的无线传感节点进行组网。仿真结果表明,所提算法在冒充性攻击下,查全率高于88%、平均响应时间低于390 ms、MAE和RMAE低于1.09%和0.95%。证明所提算法无线传感节点信息数据推荐效果较好,提高了无线传感网络通信质量和通信效率,保证了传输安全性和可靠性。Fake attacks disguised as legitimate communication entities send false information or commands to sensor nodes in wireless sensor networks,reducing the efficiency of network information data recommendation and affecting network security.Therefore,a wireless sensor information data security recommendation algorithm under impersonation attacks is studied to ensure communication quality.The trust level of neighboring nodes in wireless sensor networks under impersonation attacks is calculated,and nodes with higher trust values are selected to form an alternative recommended set of wireless sensor nodes.Data denoising,impersonation attack detection,and recon-struction processing are conducted on the recommended set of candidate nodes,and user-defined labels are mapped to standard labels to establish a node model that can evade attacks.Wireless sensor nodes that can evade attacks are acquired for networking.The simulation results show that the proposed algorithm has a recall rate higher than 88%,an average response time lower than 390 ms,and MAE and RMAE lower than 1.09%and 0.95%under impersonation attacks.It is proven that the proposed algorithm performs well in recommen-ding wireless sensor node information data,improves the communication quality and efficiency of wireless sensor networks,and ensures transmission security and reliability.
