LOPP : A Location Privacy Protected Anonymous Routing Protocol for Disruption Tolerant Network

概要

論文の詳細を見る
In this paper, we propose an anonymous routing protocol, LOPP, to protect the originators location privacy in Delay/Disruption Tolerant Network (DTN). The goals of our study are to minimize the originators probability of being localized (Pl) and maximize the destinations probability of receiving the message (Pr). The idea of LOPP is to divide a sensitive message into k segments and send each of them to n different neighbors. Although message fragmentation could reduce the destinations probability to receive a complete message, LOPP can decrease the originators Pl. We validate LOPP on a real-world human mobility dataset. The simulation results show that LOPP can decrease the originators Pl by over 54% with only 5.7% decrease in destinations Pr. We address the physical localization issue of DTN, which was not studied in the literature.
