A method for secure pairing between a sensor and a concentrator using a mobile terminal includes generating and emitting a confirmation code by the concentrator; converting by the sensor of the confirmation code into a sequence of light signals executed by at least one light-emitting diode; converting by the mobile terminal of the sequence of light signals into a sequence code; sending the sequence code to the concentrator; comparing, by the concentrator, the sequence code and the generated confirmation code: if the sequence code does not match the generated confirmation code, generating a warning; if the sequence code matches the generated confirmation code, pairing and exchanging information between the sensor and the concentrator.

Method for secure pairing between an on-board and remote sensor and concentrator

A method for the management and maintenance of an aircraft including a zone with a high degree of security, a man-machine interface of the aircraft being included in the zone with a high degree of security and necessary for a maintenance operation to be performed by a maintenance operator on a device of the aircraft to be maintained placed outside the zone with a high degree of security. The method includes: connection of a first device to the high-security zone; connection of a second device to a third device; reception of the first device by the second device of the man-machine interface of the aircraft and transfer of information for display of the man-machine interface of the aircraft to the third device; and connection of the second device to a server by means of the telecommunication network in order to obtain information from the server intended for the third device.

The present invention relates to the field of access to a high-security network, and more particularly to a device allowing secure access, for example for management and maintenance operations. There is described a connection device making it possible to connect any maintenance apparatus to a high-security network without compromising the trust of the system. The device contains a client of the maintenance application package only the inputs-outputs of which are offloaded onto the maintenance apparatus. It has authentication means and means for performing a protocol break between the maintenance apparatus and the high-security system. In this way, only said connection device needs to be trusted and the maintenance may be effected from any terminal.
