A Trust Management Scheme Based on Behavior Feedback for Opportunistic Networks

Abstract— A Trust Management Scheme Based on Behavior Feedback for Opportunistic Networks. In the harsh environment where node density is sparse, the slow-moving nodes cannot effectively utilize the encountering opportunities to realize the self-organized identity authentications, and do not have the chance to join the network routing. However, considering most of the communications in < Final Year Projects 2016 > opportunistic networks are caused by forwarding operations, there is no need to establish the complete mutual authentications for each conversation. Accordingly, a novel trust management scheme is presented based on the information of behavior feedback, in order to complement the insufficiency of identity authentications. By utilizing the certificate chains based on social attributes, the mobile nodes build the local certificate graphs gradually to realize the web of “Identity Trust” relationship.
