A Signcryption-based Secure Localization Scheme in Wireless Sensor Networks

Localization technology in wireless sensor networks has great significance for theoretical study and practical applications. However, most current localization schemes have failed to pay enough attention to security issues. In this paper, we propose a novel secure localization algorithm named signcryption-based secure localization scheme (SSLS) that allows sensors to ensure the confidentiality and integrity of their location information. Analysis shows that SSLS can enhance the security and robustness of localization through the signcryption mechanism while simulation results help to verify the performance of SSLS in that distance measurement errors can be limited within a small range.
