Abstract


With the rapid development of wireless networks , Ad-Hoc network has been widely used in many fields . Ad-Hoc network security issues , however , has not been satisfactorily resolved . How to solve the problem of the security of the Ad-Hoc network is the key to the Ad-Hoc network applications . Thesis depth study for the Ad-Hoc network security issues , given the design and realization of a concrete solution . First, the security issues of the Ad-Hoc network carried out in-depth research . Ad-Hoc network has openness , dynamic topology , and limited network resources and other new features of the Ad-Hoc network security management is unique : no central node and the node computing power , you can not use the traditional firewall technology and certification program based on static configuration . These special characteristics , the paper gives a solution , namely the establishment of a safety management based on trusted computing model (TCSM model ) to solve the security problems of the Ad-Hoc network . The TCSM model of the proposed design thinking and working mechanism , the system description . The TCSM model in the domain of the idea , the Ad-Hoc network into multiple security domains , each security domain to elect a Licensing Center (DA) is responsible for the security domain authentication and key management . The TCSM model the core of trusted computing , and developed based on the Trusted Computing DA 's election strategy . The TCSM model of Elliptic Curve Cryptography (ECC), and the establishment of key management mechanism based on ECC encryption algorithm . The TCSM model working mechanism is the focus of the study . In the realization of the design , TCSM model design registration key communication key two sets of keys as well as high and low level of security . Working mechanism analyzes the initialization , node join , key registration key negotiation communication and workflow node leaves . TCSM model , each node maintains information about the maintenance of the list of the list of information has an important impact on the entire model . Respectively from the two aspects of the feasibility and safety of a systematic analysis of the the TCSM model 's performance .
