Problems solved by technology

However, this approach will present several drawbacks
The first drawback is related to the fact that the opening of a secure communication session requires the exchange of many messages between the aircraft and the ground station, and as a result the non-negligible time for the above-mentioned session establishment will risk the need for communication between the aircraft and the ground station. risk of loss because the aircraft and ground station cannot exchange useful messages during the establishment
Another drawback is related to the fact that returning to an initial state of an unsafe communication would possibly be detrimental to the security of the communication, especially if some messages between the aircraft and the ground station at the moment of restarting the communication according to this unsafe communication state and the secure session are swapped between turn-on moments

Embodiment Construction

[0026] presented schematically in the figure 1 The device 1 according to the invention is carried on board an aircraft, especially a civil transport aircraft, and it communicates with a ground station by way of a communication link 12, especially a digital data link, which is connected by means of Multiple security level configurations related to the risk of the link being illegally invaded.

[0027] This device is used to determine whether a message received by an aircraft on link 12 should be accepted or rejected, in particular when there is a discrepancy between the level of security required by the aircraft and the level of security currently in use at the ground station under consideration. To this end, the device 1 of the invention comprises:

[0028] - message sending / receiving means 10 on the communication link 12 between the aforementioned aircraft and the aforementioned ground station, such as conventional communication means installed on board the aircraft (radio c...

Abstract

A communication method on a communication link between an aircraft and a ground station, the communication capable of being configured according to a plurality of safety levels in which, when the aircraft sends a request to a ground station to modify the safety level of the communication from a previous safety level to a new safety level and the aircraft does not receive an acknowledgement of the request by the ground station, the aircraft still accepts messages from the ground station according to the new security level. The invention further relates to the equipment for performing the method.

Description

technical field [0001] The object of the invention is a method of communication on a secure link of communication between an aircraft and a ground station, in particular when changing the level of security associated with this communication, and the aircraft includes a device capable of implementing the method. The invention also relates to a communication device on a secure link of communication between an aircraft and a ground station, in particular when changing the level of security associated with this communication, and an aircraft comprising such a device. Background technique [0002] Modern aircraft, especially civil transport aircraft, exchange information with base stations on the ground, notably air control stations or stations capable of contacting the aerospace company operating the aircraft. The information exchanged is inter alia regarding weather, aircraft maintenance and aerospace control authorizations. This information exchange is basically realized by m...
