Patent attributes
Disclosed is a method in which a portable device processor may generate an application-level certificate for an application installed on the portable device. The processor may, for example, insert an application name in a package name field of a self-signed device-level certificate of the portable device to generate an application-level self-signed certificate. A request to authenticate the application may be forwarded to the controller. The request may include the application-level certificate. The portable device processor may receive a request to form a secure communication channel between the portable device and the controller based on the authenticated application-level certificate. A controller may respond to a portable device request for services by authenticating an application-level certificate provided by the portable device so requested services may be securely provided to the portable device.
