METHOD FOR AUTHENTICATION USERS USING MULTI-CHANNEL BASED ON TRUSTED PLATFORM, APPARATUS THEREOF, TERMINAL THEREOF AND SYSTEM THEREOF

摘要

The present invention relates to a method for authenticating multi-channel users based on a trusted platform, and a service device, a terminal, and a system therefor. Authentication using an ID and a password of a user using an Internet service and an authenticating procedure through a terminal based on a trusted platform may be performed to prevent hacking against the security outside and to increase security stability by authenticating a user through an ID and a password and performing an authenticating procedure using a certificate between a terminal in which a trusted platform is mounted and a service device. An isolation environment divided into a non-security region operated based on an open operating system and a security region operated based on a security operating system is provided, authorization with respect to user authentication is assigned from a service device on a web so that an authentication procedure is performed at a security region, thereby providing a stable security function without exposing information.
