Abstract

This paper addresses the problem of secure localization in hostile environments. We propose a secure and efficient localization scheme to enhance the security function of Ultra-Wideband sensor networks. The method does not only provide strong security against distance reduction attacks, but also distance enlargement attacks. Furthermore, it is a device-independent scheme with strong function of more accurate localization. Based on Petri net, an attack-driven model is also developed. , which provides a formal method to verify our scheme when considering distance enlargement attacks. State analysis, which proves that the potential insecure states are unreachable, shows that the model can provide strong security in the environment with these attacks.
