The Research Of Secure Routing Protocol For Wireless Ad Hoc Network

As the research of wireless mobile Ad Hoc network deepen, it becomes mature gradually.Wireless mobile Ad Hoc network itself has the characteristics that distinguish it from othernetwork, making it a better application prospect, but the security problems involved in thenetwork cause some significant obstacles before the widely application of it.This thesis isbackgrounded by Ad Hoc network and based on the researches about Ad Hoc secure routingprotocols.The main research processes and results can be summarized as the following four parts:First, profound understandings of the definition of Ad Hoc network, its features, field ofapplication,structure and key technologies are necessary. As for wireless mobile Ad Hocnetwork, it analyses its fragile security attributes, security problems involved in the network, andfocuses on the discussion of security issues in Ad Hoc.Second, a detailed research about the three basic routing protocols (AODV、DSR、DSDV) ismade, which analyses the process of routing discover, response and maintenance, and brieflysummarized the security issues in it.Third, some security enhancement programs based on the three basic protocols arediscussed detailedly. And it analyses the specific mechanisms of security enhancements and theimproved protocol of its safety performance.Fourth, it proposes a new security mechanism based on source routing protocol. The newsecurity mechanism adopts a self-certified public key technology, and introduces Schnorr digitalsignature and the signature mechanism to ensure the safety of route discovery. Safety analysis ofthe new mechanism is made, and a new mechanism for the upgrading of the route safetyperformance through the NS2simulation.
