【摘要】 无线传感器网络经常被部署于开放的环境,由于节点缺乏保护,并且受计算、通信和存储空间的限制,很容易被攻击者俘获成为恶意节点.为了有效检测、定位出网络中的恶意节点,本文利用多路径传输和(t,n)门限秘密共享机制,提出一种新的无线传感器网络恶意节点定位方案,本方案的恶意节点检测不需要复杂的信任模型,不需要任何密钥加密和认证,理论分析和仿真结果表明节点只需发送少量数据就能以较高的概率检测、定位出网络中的恶意节点,并且具有较低的误检率.更多还原

【Abstract】 Wireless sensor networks are often deployed in open environment,due to the lack of protection and constrained by computing,communication and storage,the sensor nodes are vulnerable to be captured by the adversary and become the malicious nodes. In order to effectively detect and locate the malicious nodes in the network,based on multipath transmission and threshold secret sharing,a newlocation method of malicious nodes for wireless sensor network is proposed in this paper. The proposed location method of malicious nodes does not need complex trust model and any key for encryption and authentication,the analysis and simulation results showthat it can detect and locate the malicious nodes at higher probability when the node only send small amount packets,and has lower error detection probability.更多还原
