Trusted Computing-Based Double Factor Authentication for Mobile Terminals

Due to some security issues of varieties of mobile access technologies, we need a new supporting infrastructure that can be able to support more efficient and secure ways to authenticate users and devices arises. To meet this goal, in view of current security issues of mobile terminals, we analyzed the idea of trusted computing, describe the user authentication model of TCG(Trusted Computing Group) trusted platform, then we presented a authentication scenario that used hash function and fingerprint encrypted by OTP(One-Time Password), brought forward a method of double factor authentication in the mobile terminals, this scenario also can solve some security issues such as decimal attacks and fingerprints leakage, besides, field isolation technology and access control policy are used to verify security of terminals.
