The invention relates to the technical field of power systems. The invention provides an identity authentication and eavesdropping positioning method for power line carrier communication equipment. The method comprises the following steps: S1, collecting a signal of each child node; s2, extracting a node fingerprint from the signal of each child node; s3, performing identity authentication according to the node fingerprint of each child node and a corresponding reference node fingerprint in a preset node fingerprint database; and S4, if the identity authentication is not passed, establishing a double linked list according to the topological relation among the plurality of child nodes, and carrying out eavesdropping positioning according to the double linked list. The eavesdropping positioning efficiency can be improved, and the reliability is high. 本发明涉及电力系统技术领域。本发明提供一种电力线载波通信设备身份认证及窃听定位方法，所述方法包括以下步骤：S1，采集每个所述子节点的信号；S2，从每个所述子节点的信号中提取节点指纹；S3，根据每个所述子节点的节点指纹和预设节点指纹库中对应的基准节点指纹进行身份认证；S4，如果身份认证不通过，则根据所述多个子节点之间的拓扑关系
