Abstract:

Aiming at the definitionproblem of that the trust definition and the current model of trust has not been establishedve no common definitionsrepresentations currently ,The general description to the definition the and model of the trust must be needed, therefore we this paper presents a trusted computing platform model based on existing computer network, whichby makes full use of using the versatility of existing computer and network platform and it’s versatility. Through By putting the existing computing layered platforms into different logical trust layers, not onlyit reduces the difficulty of the implementation to theing trusted computing platform models but also , and improves its flexibility, scalability and efficiency of the models. At the same time, tAhe model building the credibility of a complete trusted chain is established based on in the starting phase to of the client system, thereby ensuring to ensure the security of trusted computingthe platform security. The Implementation results of the implementation to the prototype system showed that:t in the system, all the computers and their networks in the system constitute a unified platform for trusted computing, which mademakes the transfer of trust from the the user to the the user come true, and then realizeand realizes the true user experience for the trusted computing between users.
