Abstract
An avionic equipment unit, intended to be on board an aircraft, including a calculating module configured to calculate a signature associated with a data field, the calculated signature depending on the data field, and a transmission module configured to transmit a message to another avionic equipment unit on board the aircraft, the message including the data field and the associated calculated signature, the calculated signature being unique for each data field and for each respective message transmission.

An avionic equipment unit, intended to be on board an aircraft, the avionic equipment unit comprising:
- a module for calculating a signature associated with a data field, the calculated signature depending on the data field;
- and
- a transmission module configured to transmit a message to another avionic equipment unit on board the aircraft, the message including the data field and the associated calculated signature, wherein the calculated signature is unique for each data field and for each respective message transmission, the signature further being calculated as a function of a preceding signature associated with the data field of the last message transmitted by the transmission module.
A method for transmitting a message via an avionic equipment unit, intended to be on board an aircraft, the method comprising:
- calculating a signature associated with a data field, the calculated signature depending on the data field;
- and
- transmitting a message to another avionic equipment unit on board the aircraft, the message including the data field and the associated calculated signature,
- wherein the calculated signature is unique for each data field and for each respective message transmission, the signature further being calculated as a function of a preceding signature associated with the data field of the last transmitted message.
