A portable communication apparatus has a man-machine interface, a controller, an operating system, a local storage device for storing a first application, a secure resource which is only accessible from the operating system, and a wireless interface 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 the first application is executed by the controller and the operating system. The man-machine interface also provides interaction between the user and a second application originating from the remote device. Only the operating system can provide a security indicator through the man-machine interface. The security indicator indicates a secure connection between the secure resource and either the first application or the second application, whichever is interacting with the man-machine interface. |
