1. Communication method comprising:
- receiving digital data by at least one aircraft from a ground station, prior to a flight, the digital data including predetermined information generated at the ground station corresponding to the flight, the at least one aircraft performing the flight based on the digital data received from the ground station,receiving by the at least one aircraft at least one identification information item identifying the received digital data,after the flight, digital signing said digital data received by said aircraft prior to the flight to generate a digital signature, andtransmitting said digital signature to the ground station after the flight without transmitting any of the received and signed digital data to the ground station,wherein said digital signature is transmitted with the received at least one identification information item identifying said received and signed digital data, said identification information item being of lesser size than said received digital data.

Abstract
A communication method intended to ensure the receipt of digital data by at least one remote entity, and an associated system, in particular in the context of data transfer with an aircraft, includes receiving of numerical data by at least one remote entity, digital signing of the data received by the remote entity so as to generate a digital signature, and transmitting the digital signature to a local entity. The digital signature is transmitted with at least one identification information item for the received and signed data. The identification information item is smaller size than the received data.

11. Communication system within an aircraft comprising:
-
means for receiving digital data on a communication network from a ground station, prior to a flight, the digital data including predetermined information generated at the ground station corresponding to the flight, the aircraft performing the flight based on the digital data received from the ground station, means for receiving at least one identification information item identifying the received digital data, means for digitally signing, after the flight, said digital data received prior to the flight to generate a digital signature, and means for transmitting said digital signature on said communication network to the ground station after the flight without transmitting any of the received and signed digital data to the ground station, wherein said digital signature is transmitted with the received at least one identification information item identifying said received and signed digital data, said identification information item being of lesser size than the received digital data.
