DEVICE FOR SECURING A CLIENT APPLICATION FOR A SYMBOLOGY DISPLAY SYSTEM OF THE CLIENT-SERVER TYPE

摘要

The device according to the invention, which makes it possible to secure a client application, including an acquisition and processing module of measured properties (GM) to generate properties of interest (GI); a lookup table associating each dynamic variable (VD) of each of the graphic objects to be maintained with a property of interest (GI); and a module for generating commands capable of issuing a command (C) to the server application. The device includes dedicated means for securing the operation of said acquisition and processing module; dedicated means for securing said lookup table; and dedicated means for securing said command generating module.

1. A device for securing a client application for a symbology display system of the client-server type onboard an aircraft, said client application using instantaneous values of measured properties relating to flight of the aircraft to generate a command to modify a graphic object intended to be interpreted by a server application of said display system, said graphic object corresponding to a symbol to be displayed in the form of an image on a graphic device of said display system, wherein said client application includes:
an acquisition and processing module using instantaneous values of measured properties relating to flight of an aircraft as inputs to generate instantaneous values of properties of interest; a lookup table associating each dynamic variable of a set of dynamic variables of each of the objects maintained by the server application with a property of interest, said lookup table assigning the instantaneous value of the corresponding property of interest as the instantaneous value of a dynamic variable; and a software module for generating commands and issuing a command to the server application, and wherein the device includes:
dedicated software configured to secure the operation of said acquisition and processing module;dedicated software configured to secure said lookup table; anddedicated software configured to secure the operation of said command generating module.
