Wormhole attacks can cause serious disruptions to the network topology in disaster rescue opportunity networks. By establishing false Wormhole(WH) links, malicious nodes can mislead legitimate paths in the network, further causing serious consequences such as traffic analysis attacks (i.e., by eavesdropping and monitoring exchanged traffic), denial of service (DoS) or selective packet loss attacks. This paper uses rescue equipment (vehicle-mounted base stations, rescue control centers, etc.) as an effective third-party auditor (TPA), and combines the commonly used Z-Score (Standard Score) data processing method to propose a new detection method based on pure mathematical statistics for detecting wormhole attacks. Finally, we perform a large number of simulations to evaluate the proposed method. Since our proposed strategy does not require auxiliary equipment such as GPS positioning and timers, as a pure data statistical analysis method, it is obviously more economically valuable, feasible, and practical than other strategies in disaster relief.
