Abstract
The present invention provides an application authentication system capable of authenticating an application on a terminal device, which does not have a secure information concealing area, by a secure device. In an application authentication system in which a secure devicefitted to a terminal devicethat has no secure information concealing area authenticates an applicationstored in the terminal device, the secure deviceauthenticates an application running meansstored in an unwritable areaof the terminal device, and also authenticates the application based on a process applied to the applicationby the application running means to request an access to the secure device. Since the terminal authentication by the secure device and the application authentication executed within the terminal device are coupled in combination, the secure device can authenticate the application operated on the terminal device without the secure information concealing area.
