| Summary: | 碩士 === 南華大學 === 資訊管理學研究所 === 96 === Near-Term Digital Radio (NTDR) network is a kind of mobile ad hoc network (MANET) in which mobile nodes are assigned into different clusters. Therefore, it can let the nodes to communicate with each other efficiently in a large area. Despite several NTDR protocols have been proposed, there still lacks an efficient secure one. Accordingly, in this paper, we propose a new method based on ID-based bilinear pairings to overcome the unsolved security problems nowadays. After our analysis, we conclude that our scheme is the first protocol for NTDR network that is not only secure but also very efficient. We also propose the authentication scheme for smart card system and show that the traditional smart card authentication techniques inevitably suffer the parallel session attack. Henceforth, we propose a novel scheme based on ID-based bilinear pairing which not only can avoid this attack.
