The time required for authentication (IV) is reduced by first transferring first data (D) in a not secured and then in a secured manner, wherein the data being used by means of a processor (CPU) of the first module (1) for a first process (III). The data (D) transferred in a not secured manner are compared with those transferred in a secured manner and if there is a difference, results from the first process (III) are discarded.
