Abstract
A method for verifying the integrity of data transmission between a main upstream unit () and a main downstream unit (). The method includes the implementation of the following steps: a data-processing module () of the main upstream unit () generates a first frame (T) including a packet (P) of data to be transmitted and a cyclic redundancy code (E) of the packet (P); encapsulates the first frame (T) in a second frame (T) which also includes a cyclic redundancy code (C) of the first frame (T); encapsulates the cyclic redundancy code (E) of the packet (P) in a third frame (T); the data-processing module () of the at least one auxiliary upstream unit () compares each of the cyclic redundancy codes (E) extracted from the first frame (T) with those extracted from the third frame (T); and confirms the integrity of data transmission to the main downstream unit () only if the comparison is positive.
