碩士 === 長庚大學 === 電機工程研究所 === 91 === Ad hoc networks are organized by collection of mobile communication devices without fixed infrastructure, and with no pre-determined organization of available links. There are various challenges that are faced in the Ad-hoc environment. These are mostly due to the resource poorness of these networks. They are usually set up in situations of emergency, for temporary operations or simply if there are no resources to set up elaborate networks. Ad-hoc networks therefore throw up new requirements and problems in all areas of networking. The solutions for conventional networks are usually not sufficient to provide efficient Ad-hoc operations. The inherent quality —wireless and mobility- of wireless mobile networks and the lack of centurial control units, the security is usually a weaker point for ad hoc networks. Public key infrastructure(PKI) offer the authentication and key exchange scheme to achieve such security goals as privacy, non repudiation, and integrity. The traditional public key infrastructure must have a centurial control unit call certificate authority(CA) for issuing certificates, revoking certificates, creating and publishing certificate revocation lists, and key and lifecycle management. Thus it cannot applied to wireless ad hoc networks. In this thesis, a identity-based(ID-based) key exchange and authentication protocol is proposed to remedy the disadvantage.
