Abstract
The invention in particular has as an object the control of execution of software commands of a data-processing system in an aircraft cockpit comprising means for allowing a user to call up these commands. For these purposes, the means making it possible to call up these commands initially are locked in order to block calls to software commands. At the time of reception of an information item for unlocking these means, they are unlocked and the software commands may be called up. The software commands may be called up via the call-up means only if these means are in an unlocked state.
Claims20
A method for protecting at least one software command of a data processing system of an aircraft cockpit, said data-processing system comprising a call-up mechanism allowing a user to call up said at least one software command, this method comprising:
- locking said call-up mechanism in order to block the call up mechanism from sending a call to initiate the at least one software command;
- receiving in the data processing system an information item for unlocking said call-up mechanism of said at least one software command;
- verifying in the data processing system at least one predetermined rule, said at least one predetermined rule being dependent on a characteristic of said at least one software command and/or a configuration of a device which includes the data processing system;
- and
- in response to said receiving of said information item for unlocking and said step of verifying, unlocking said call-up mechanism such that said at least one software command is able to be called up via said call-up mechanism of said at least one software command only if said call-up mechanism is in an unlocked state.
