摘　　要：通过对无线传感器网络节点安全定位技术的研究和分析,采用基于跳数的节点定位算法思想获取定位参照信息,提出了一种与硬件无关的基于跳数的节点安全定位算法——HOP-GDSL,该算法用设计的信标节点信息传递协议提供包的认证、保护跳数信息,用现有的锚节点检测虫洞攻击。经仿真实验证明,该算法能有效抵抗恶意节点攻击,实现节点正常定位,并对虫洞攻击有较高的检测率。This paper is based on the secure localization properties of nodes in Wireless Sensor Networks（WSNs）.It is put forward a secure localization algorithm of nodes based on hop-count called HOP-GDSL,which adopts the method of hop-count based localization algorithm of nodes to get location reference information.The algorithm adopts the message propagation protocol of beacon nodes designed by us to authenticate packet and protected message of hop-count,And existing anchor nodes to detect wormhole attacks is adopted.Theoretical analysis and simulation all prove the superiority of the algorithm.
