Trusted Network Model Based on Trusted Platform Module

In order to solve the problem of the establishment of network trust,this paper brings up a trusted network model based on Trusted Platform Module(TPM) security chip,which is based on the theory of trusted computing and trusted network access technology.This model describes the establishment of trusted chain and expands the trusted chain to the network,then gives the model structure and information flow analysis,and makes the trust of metric computation.Through performance analysis,results show that the network model has a strong robustness and high credibility.
