Chain measurement mechanism of trusted computing don't easily extend to all applications in the terminal

so it is difficult for the terminal to always maintenance trust of the dynamic running environment of the terminal.To collect trustworthiness evidence in an objective

genuine and comprehensive way

this paper proposes a trustworthiness evidence collection mechanism of trusted terminal running dynamic environment.Firstly

a trusted evidence collection agent

whose creditability is assured by the measurement function of trusted platform module (TPM)

is introduced by an application system in the terminal

the main function of which is collecting the information of the terminal dynamic running environment including memory

process

CPU

port of net

disk files

configure data and so on

and saving those evidences in Database or files by TPM.This mechanism has good scalability for various trustworthiness evaluation models.This paper also implements a prototype of the agent in Windows platform

and analyses the performance of agent in a local network distributed computing environment.This application demonstrates the feasibility of this mechanism.
