Method of verifying data communication integrity in an aircraft which has first and second data generating and sending entities. Data generated at the first entity is sent to the second entity as messages via a number of intermediate entities. The data communication is a blockchain with blocks, each being added to the blockchain by one of the entities and including a cryptographic hash representative of the prior block, thus linking the blocks. The method includes: a) logging a message subgroup and cryptographic hash at one or more of the first, second and intermediate entities; b) collecting message logs from each entity for verification; c) comparing messages sent by the first entity and messages received by the second entity; and d) if not all messages have arrived at said second entity, comparing message logs of intermediate entity(ies) with the message log of the first entity to identify where loss occurred.
