Abstract


Computer networking is one of the fastest growing technologies in our culture today, and it makes human life more convenient than before. But it is also a risk to use the convenient shared resources of network. So, the problems of network security are paid more attention to and become key points of research on network technology. For personal computer, only take measures to hardware and bottom software can it’s security is improved. Based this idea, the trusted computing born.Application of trusted computing in Distributed Database Server System is Trusted DDSS, based on DDSS, building of trusted chain, theory of management of authorization are researched. A trusted computer is the trusted root, and from it the worthiness transferred step by step, finally the worthiness expands to the whole system. In order to make the DDSS a trusted one, some technologies are imported such as tickets and Role-Based Access Control. A delegation model also is presented by defining concepts such as authorization root delegation subject. By adopting these technologies above the security of DDSS is improved based on its reliability, finely a trusted system appears.
