Executive Summary

Recent advances in wireless networking technologies, along with ubiquitous sensing and computing, have brought significant convenience for location service. The localization issue in wireless sensor networks under the non-adversarial scenario has already been well studied. However, most existing localization schemes cannot provide satisfied location service under the adversarial scenario. In this paper, the authors propose an attack-resistant localization scheme, called TSCD secure localization, to overcome the distance-consistent spoofing attack in wireless sensor networks. The main idea of the TSCD scheme is to firstly apply the temporal and spatial properties of locators to detect some attacked locators, and then utilize the consistent properties of the attacked locators and legitimate locators to find out other attacked locators.
