Abstract
A secure display device is designed to display on a screen a first set of information edited by an open operating system. A secure operating system resident in a dedicated circuit edits a second set of information. A filter allocates, independently of the open operating system, a first zone of the screen to the first set of information and a second zone of the screen to the second set of information. The zones and can have a non-zero intersection and any value. A real video memory is used for transferring the two sets of information to the screen under the sole control of the secure operating system so as to produce a secure display of the second set of information.
