Abstract: In recent years, the security issues on network device have been increasingly prominent. If the network devices are not trusted, all computers in the net are likely to be in the risk of being attacked and all data being stolen. Whether the network devices access network in security or not directly affects the safety of the whole network. It presents a trusted authentication method based on IMC/IMV for network devices. Under this method, the traditional platform identity authentication is carried out and the trusted status verification of the platform is carried out too. The network device’s trusted status information is collected by Integrity Measurement Collector（IMC） and verified by Integrity Measurement Verifier（IMV）, to which the information are submitted by multiple rounds protocol interactions. The final experiments show that this authentication method effects little on system performance when the network device are under trusted authentication.
