A PORTABLE COMMUNICATION APPARATUS HAVING A MAN-MACHINE INTERFACE AND A METHOD FOR ITS OPERATION

摘要

A portable communication apparatus (1) has a man-machine interface (2-5, 21), a controller (23), an operating system (25), a local storage device (24) for storing a first application (26, 27), a secure resource (29) which is only accessible from the operating system, and a wireless interface (30-32) for connecting the portable communication apparatus to a remote device. The man-machine interface provides interaction between a user of the portable communication apparatus and the first application when executed by the controller and the operating system. The man-machine interface also provides interaction between the user and a second application (28) originating from the remote device. The operating system (25) and only the operating system can provide a security indicator (22) through the man-machine interface (2-5, 21). The security indicator represents a secure connection between the secure resource (29) and the one of the first and second applications (26-28), which currently uses the man-machine interface.
