Based On Credible Model Of The Component Platform

With the development of the computers and the embedded systems, digital family develops rapidly from its conception raised to the technological application. It includes a network equipped with a broadband embedded and many domestic appliances can be connected to this network. Through it, intercommunication and interoperation can be done among the connected appliances, then, we can realize many functions such as digital transition, communicative service, entertainment share and smart home, etc. Various applications based on digital family were produced and, representatives of whom multimedia, entertainment, office and network management included will be more and more populated.Modularization and software reuse are always the subjects of software engineering. For the current technology, component-based software is mainly used to design the general purpose software, but hasn't been popular in the field of embedded software essentially because it's very complicated in the relationship of embedded software and the architecture of the software. I studied CORBA (Common Object Request Broker Architecture by OMG (Object Management Group). And try to find a way to build it, make it has both theoretic and practical value.In the world, trusted computing technology has been popular in research. This thesis reaching in digital family technology, aims to better data protection and more reliable service.The research on this thesis based on a component-based platform of application and development facing digital family, mainly lies on trusted authentication technology, component-based technology, trusted-component service. Because the study based on component-based platform, component-based technology must be realized in the project. Moreover, a service mode will be built on a component-based platform, these services will be developed and realized in the platform, but running in the ultra-server which is an embedded server if or support of the terminal device in the digital family. During the process of the development, it's necessary for trust-guarantee mainly from operating system, network protocol, middle level and software. Framework study will be realized in the technologies of trusted-authentication, component-based and trusted component-based.
