A Security Authentication System Based on Trusted Platform

An authentication system based on trusted platform is presented in distributed network, network nodes are distributed in each domain, the domain authentication server based-TPM granted a certificate to each trusted member of domain and authorize trust token to access network source in different domain, in this paper, many security technologies are applied, member with trust token can span domain boundaries, transmit security message and access resource, authentication can prevent message from tampering and counterfeiting based on Dolve-Yao attack, and shorten the response time of authentication.
