Abstract
The present disclosure relates to the secure transmission of an aircraft trajectory that is to be flown or that has been flown. A ground-referenced description of the trajectory of the aircraft expressed in ground-referenced parameters is converted, using a description of an imaginary atmospheric model describing imaginary atmospheric conditions along the trajectory, into an air-referenced description of the aircraft trajectory expressed in air-referenced parameters. For decryption, knowledge of the imaginary atmospheric conditions allows the air-referenced description of the aircraft trajectory to be converted back into the ground-referenced description of the aircraft trajectory. Thus, the ground-referenced trajectory may be though of as the plain text, the imaginary atmospheric model as the cipher key and the air-referenced trajectory as the cipher text.
