碩士 === 國立臺灣科技大學 === 資訊工程系 === 97 === A mobile ad hoc network (MANET) is a mutually trusted network without an infrastructure. In MANETs, each node not only acts as a client but also serves as a router; therefore, messages are transmitted via a multi-hop manner and possibly known by the forwarding node. This gives malicious nodes a chance to temper or drop packets sent by other nodes. This makes the security issue, in particular, secure routing, very important in MANETs. In the past, secure routing protocols for MANETs were always designed under the assumption that a third party serving as a key distribution (authentication) center exists. Since this assumption is not reasonable, a secure on-demand routing protocol without the third party (SORWT) is then proposed in this thesis. SORWT is composed of the rename announcement mechanism, one-by-one signature mechanism, fake name mechanism, and multipath probing security mechanism and has the ability of authentication, integrity, non-repudiation, confidentiality, and anonymity without the third party. Through simulations, we show that SORWT can outperform SRPTES and SAODV reported in the literature to prevent it from the wormhole attack, blackhole attack, rushing attack, and dropping of packets.
