    [0001] TECHNICAL FIELD OF THE INVENTION The present invention relates to the field of communication on a wireless network of an aircraft. In particular, the invention relates to a method and a system for automatic and secure connection of a mobile device to a wireless network of an aircraft. Mobile electronic devices are increasingly used in aircraft. As an example, the paper-based navigation manuals and charts that the pilot takes with him into the cockpit are currently being replaced by an electronic flight bag (EFB) in the form of a tablet or laptop computer. less heavy and more efficient for flight management than paper documents. In addition, a maintenance operator may also need to connect a laptop to the aircraft network for alerts or anomalies detected in the aircraft. Thus, it is convenient to use a wireless network type Wi-Fi to allow the connection of an EFB, a tablet or a laptop to the network of the aircraft. For example, it is advantageous for the maintenance operator to be connected to the aircraft network while moving in or around the aircraft to carry out maintenance operations. Connecting to a wireless network usually requires authentication settings (for example, passwords, keys, or certificates). Managing these parameters for a whole fleet of aircraft and mobile devices is very complex, expensive and requires a lot of work. Indeed, it is not easy to manage the configuration of the different aircraft networks and the creation and deployment of authentication parameters on a multitude of mobile devices to be connected to the different wireless networks. In addition, it is necessary to manage the synchronization of the configuration of mobile devices vis-à-vis that of the networks of different aircraft of the airline.
    [0002] In addition, there must be a rapid organizational response to any security threats to aircraft networks. Indeed, in the case where an attacker has access to a password or a certificate by flying for example an EFB, it is important to be very reactive to update the configuration of all the wireless networks of the aircraft concerned and than all EFBs connecting to these networks. Of course, one must already be aware that the EFB has been stolen or compromised. Regarding the user, it is important to check that he is connected to the correct wireless network for example that of the cockpit of the aircraft and not to that of the cabin or the wireless network of a nearby aircraft or even to that of the airport. For this, the user may need to know what is the right wireless network and to select it manually, which represents for him an additional task. In particular, there may be two contingencies. In a first case, the wireless network is already configured but the user is still connected to another network and in a second case, the wireless network is not configured at all. In the first case, you have to go to the Wi-Fi settings and find the right network to connect to it. In the second case, it is necessary to configure it by entering the parameters by hand knowing that the manual entry of a long passphrase (i.e. a password having a large number of characters) can be very tedious. The object of the present invention is therefore to provide a method and a connection system remedying the aforementioned drawbacks, in particular by automating the management of the connection parameters while increasing the security of the connection between a mobile device and a network without wire of an aircraft. OBJECT AND SUMMARY OF THE INVENTION The present invention aims at automating and securing the connection of a mobile device to a wireless network of an aircraft comprising an access point, and relates to a connection system comprising: a module of management installed in a secured area of the aircraft and connected to said access point, said management module being configured to generate connection parameters and to configure said access point according to said connection parameters, and - a module of wireless transmission installed in said secure zone and connected to said management module, said transmission module being configured to deliver said connection parameters to said mobile device in a range restricted to said secure zone, said connection parameters being adapted to enable said device mobile to connect by a simple scan and securely on said wireless network of the aircraft via said poise access. This system allows autonomous organizational management of security parameters and in particular, automatic and secure updating of the connection and configuration parameters of the access point, while reducing human actions to a minimum. BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the system and method according to the invention will emerge more clearly on reading the description given below, by way of indication but without limitation, with reference to the appended drawings in which: FIG. . 1 schematically illustrates a system for automatic and secure connection of a mobile device to a wireless network of an aircraft, according to one embodiment of the invention; FIG. 2 schematically illustrates a connection system, according to a preferred embodiment of the invention; - Figs. 3A and 3B schematically illustrate a connection system, according to first and second embodiments of the invention; and - FIG. 4 schematically illustrates the steps of a connection method, according to one embodiment of the invention.
    [0003] DETAILED DESCRIPTION OF EMBODIMENTS The principle of the invention consists in using a secure zone to automatically manage and deliver connection parameters inside the secure zone allowing a mobile device to connect thereafter to a point d wireless access safely. A secure zone is defined as an area for which access is restricted to authorized and trusted persons and users of the wireless network in question. Fig. 1 schematically illustrates an automatic and secure connection system 1 of a mobile device 3 to a wireless network 5 of an aircraft, according to one embodiment of the invention. This figure is also an illustration of a method of connecting a mobile device to a wireless network of an aircraft, according to one embodiment of the invention. The wireless network 5 is for example a Wi-Fi network comprising at least one wireless access point 7. For example, the Wi-Fi network is implemented according to WPA-PSK (or WPA2) technology offering a very good security using a passphrase (or secret phrase, ie a word password composed of a large number of characters) PSK type (pre-shared key) shared for example by all users. In another example, the Wi-Fi network is implemented using WPA-EAP technology with EAP-TLS which offers excellent security by using a private key and certificates. Thus, a mobile device provided with suitable connection parameters (certificate, key or passphrase) can connect to the wireless network 5 via the access point 7. According to the invention, the connection system 1 comprises a module management 9 and a wireless transmission module 11 both installed in a secured area 13 of the aircraft. For example, the secure area 13 may be a cockpit, an avionics bay, a cargo bay, a landing gear bay, or a rest area of the crew which is of course only accessible to aircraft. authorized and trusted users. In another example, the secure zone 13 may be the cabin of the aircraft in the specific case where the Wi-Fi network is intended for the passengers of the aircraft only as authorized and trusted persons and passengers there have access. The management module 9 is connected by wire means to the wireless access point 7 and the wireless transmission module 11. Advantageously, the wireless access point 7 is also installed in the secure zone 13. Optionally, other access points may also be installed in other areas of the aircraft.
    [0004] The management module 9 is configured to generate connection parameters and to configure accordingly the access point (s) 7 according to the connection parameters generated. It will be noted that the connection parameters comprise security accreditations in the form of certificates, keys or passphrases according to the standard used of the wireless network 5 and, advantageously, these parameters are valid for a limited and predetermined time, and therefore regularly renewed. Several connection parameters can be valid at the same time to connect to the access point 7. In addition, the management module 9 is configured to transmit the connection parameters via the wired connection to the wireless transmission module 11. The latter is a high reliability module installed only in the secure area 13 and having a range restricted to this area. The wireless transmission module 11 is configured to deliver the connection parameters received from the management module 9 to a mobile device 3 located in the secure zone 13. Thus, no broadcast of the connection parameters is possible to the Outside the secure zone 13. In practice, the delivery of the connection parameters is performed only over a range of just a few centimeters, or over a range of several meters in a specific direction. Furthermore, the connection parameters are adapted to allow the mobile device 3 which has received these parameters to connect for example by a simple scan and securely on the wireless network of the aircraft via the access point 7 without thread. Of course, once the mobile device 3 is connected to the wireless network 5 of the aircraft, this device 3 can be moved safely in other areas of the aircraft that are not necessarily secure. Indeed, the proven connection of the mobile device on the wireless network of the aircraft via said access point is provided on a predetermined area that can cover the aircraft. This predetermined zone covers at least said secured zone and may cover, as the case may be, an area of a diameter substantially greater than or equal to the length of the aircraft or at both ends furthest from the aircraft.
    [0005] Fig. 2 schematically illustrates a connection system, according to a preferred embodiment of the invention.
    [0006] According to this embodiment, the management module 9 comprises a parameterization unit 15, a configuration file unit 17, a pseudo-random number generator 19, and an identification generator 21. These units and generators are, for example, set implemented by logic means or integrated applications in the management module 9. The latter is for example a computer usually comprising input and output devices, a processing unit, and a memory that can comprise a computer program comprising code instructions adapted to the implementation of the connection method according to the invention.
    [0007] The parameter unit 15 is adapted to receive a predefined trigger event intended to trigger the process of creating the connection parameters. More particularly, the setting unit 15 is configured to remain waiting for the triggering event and once it has been received, the setting unit 15 is configured to proceed with the production of the connection parameters.
    [0008] Advantageously, the triggering event 23 is configurable and can be programmed beforehand in the configuration file unit 17. In effect, the configuration file unit 17 makes it possible to define this triggering event among a set of events that can comprise external events 23a, such as, for example, events originating from avionic parameters (typically a flight phase change received for example by an ARINC interface 834) or a predetermined date, as well as other types of events such as for example a request 23b of a mobile device, a user via an application or a reset 23c. In addition, the configuration file unit 17 is intended to define the nature and properties of the connection parameters to be produced and the method of transmission of these parameters to the wireless transmission module 11 and to the access point 7. In addition, the pseudo-random number generator 19 is configured to generate a random sequence of numbers. The latter is used by the parameterization unit 15 to produce the connection parameters and to configure the access point (s) 7.
    [0009] The configuration parameters are directly sent by the parameterization unit 15 to the wireless access point 7. On the other hand, before the connection parameters are transmitted to the wireless transmission module 11, they are first formatted by the identification generator 21. In fact, the latter is configured to translate the connection parameters into a language. adapted or compatible with the transmission mode of the wireless transmission module 11.
    [0010] Fig. 3A schematically illustrates a connection system, according to a first embodiment of the invention. According to this first embodiment, the wireless transmission module 11 comprises a Near Field Communication (NFC) type near field communication interface 111. In this case, the identification generator 21 is configured to adapt the parameters of connection to the NFC communication technique before transmitting them to the wireless transmission module 11. Thus, a mobile device 3 (comprising wireless connection means, connection parameter recovery means, configuration means and an NFC interface) can easily connect to the wireless transmission module 11 in order to retrieve the parameters. connection. These parameters will automatically configure the mobile device 3 so that it can connect to the wireless network 5 of the aircraft. Fig. 3B schematically illustrates a connection system, according to a second embodiment of the invention.
    [0011] According to this second embodiment, the wireless transmission module 11 comprises a screen 211 and in this case, the identification generator 21 is configured to translate the connection parameters into a QR matrix code before transmitting them to the module. wireless broadcast 11. The latter displays the QR code on its screen 211 waiting for it to be read by a mobile device 3. Of course, it will be noted that the screen 211 displaying the QR code is not visible outside the secure area 13. Thus, a mobile device 3 comprising a QR code reader (for example a camera) in addition to the connection, recovery and configuration means, can scan the connection parameters from the screen 211 of the transmission module 11 wireless.
    [0012] Alternatively, the wireless transmission module 11 may include a printer for printing the QR code on paper, the user can then scan the connection parameters by means of his mobile device 3. FIG. 4 schematically illustrates the steps of a connection method, according to one embodiment of the invention. In the initial step, the management module 9 is in a listening state of predetermined events or environmental signals. When the parameterization unit 15 receives a triggering event (for example an external signal represented by the arrow El), it then checks with the configuration file unit 17 (arrow E2) whether this signal corresponds to a triggering event 23 predefined. In the negative case, the parameterization unit 15 remains listening for other signals, otherwise (ie, if the signal received corresponds to the expected triggering event), it calls (arrow E3) the pseudorandom number generator 19 who will return a series of random numbers. The parameter unit 15 uses this sequence of random numbers to generate connection parameters (wireless network name, passphrase, certificate, key, etc.). For example, for a long-haul aircraft, the triggering event programmed in the configuration file unit 17 may be the pre-flight phase of the aircraft. Thus, new connection parameters are generated at each flight. On the other hand, for a small or medium-sized aircraft, the triggering event is for example, a specific time or a specific date. Thus, new connection parameters are generated for example every 12 or 24 hours, which prevents the pilot to reconnect before each take-off when he is still in command of the same aircraft for a subsequent flight. In another example, the triggering event may correspond to a request from a mobile device of a maintenance operator. According to yet another example, the triggering event corresponds to a reset of the management module by means of, for example, a reset button. The reset button can be a physical button or a logic button in a reset settings application. This makes it possible to generate new connection parameters as soon as an attack (or theft) of a mobile device 3 is noted.
    [0013] Moreover, once the connection parameters are generated, the parameterization unit 15 transmits (arrow E4) these parameters to the authentication means of the wireless network 5 to configure the access point 7. Thus, the point Access can recognize new connection settings.
    [0014] Likewise, the parameterization unit 15 transmits (arrow E5) the connection parameters to the identification generator 21 so that the latter translates these parameters into a language compatible with the transmission mode of the wireless transmission module 11. Then, the identification generator 21 transmits (arrow E6) the connection parameters to the wireless transmission module 11 in a language adapted for example to an NFC communication technique or QR code. These connection parameters remain in the wireless transmission module 11 awaiting a user equipped with a mobile device 3 requesting to be connected to the wireless network. In the case where the wireless transmission module 11 has an NFC interface 25, it is sufficient for the user to approach (dashed arrow F1) the mobile device 3 to the wireless transmission module 11 in order to scan the parameters. connection. If the NFC is on the physical medium of the mobile device 3, the scan will be done naturally and automatically. Note that in the case of a connection according to NFC technology, the wireless resignation module 11 can send (dashed arrow E7) a signal to the setting unit 15 each time a mobile device 3 reads the parameters. connection. Optionally, this allows the parameterization unit 15 to generate new connection parameters for each mobile device 3 in order to properly identify and differentiate the different mobile devices.
    [0015] In the case where the wireless transmission module 11 has a screen 211 displaying a QR code, the user must position (dashed arrow F1) the camera of the mobile device 3 so as to see the screen 211 in order to scan the connection settings. Thus, the connection system according to the invention allows automated, secure and autonomous organizational management of the connection parameters. Indeed, it is sufficient to configure the connection system only once to the installation and then the reconfiguration of the access point and mobile devices are fully automated. In addition, the user no longer has to manually enter the connection parameters but just to do a scan. In addition, scanning via wireless technology in the secure area automatically connects to the correct wireless network.
    [0016] Furthermore, in the event of compromise of the safety parameters, the risk is limited to the validity period of these parameters which may correspond to a single flight or a day depending on the configuration and on a single given aircraft. In addition, to discover the compromise, a simple press of a reset button allows you to modify the configurations.
