Abstract
According to the application, a method for transmitting an encrypted aircraft related message is disclosed. A message is provided at one of a ground computer system or an aircraft computer system. The aircraft related message is arranged into data packets and at least one of the data packets is encrypted with an encryption key to obtain at least one encrypted data packet. The at least one encrypted data packet is transmitted from a sender to a recipient, wherein the sender is one of the ground computer system or the aircraft computer system, the recipient is the other one of the ground computer system or the aircraft computer system. The at least one encrypted data packet is received by a computer system of the recipient. A step of deciding whether the message is intended for the recipient'"'"'s computer system is provided. The step of deciding comprises an attempt to decrypt the at least one encrypted data packet with an decryption key, and the decryption attempt comprises analyzing of the message content. If it is decided that the decryption that the message is intended for the recipient, a step of processing the decrypted data message by the recipient'"'"'s computer system is provided.
