摘要：Disruption tolerant networking (DTN) technology is designed to deal with the intermittentconnectivity among mobile nodes due to mobility, short range radios or terrain obstacles. Our schemes utilize bothquery and data replications to enhance the query success rate. Besides designing efficient query and data disseminationschemes, one needs to consider the security aspects since sensitive data should only be accessed by authorizedpersonnel. In this paper, we present a data-centric security solution for an information retrieval system which wedesign for DTN environments through the Access Control mechanism through Multi Authority specific Attributebased encryption (MA-ABE). We also describe the preliminary prototype that we have built. Both theoreticalanalysis and simulation results demonstrate that our proposed scheme is more efficient than the CP-ABE scheme interms of computational and communication overhead under comparable security levels while providing message andIdentity privacy.
