The module for securing data (1) is directed by an external microprocessor and consists of an interface (10) which is connected to circuits (11,12,13). The circuits secure data received from and transmitted towards the interface and each circuit has a securing input/output section (11a-13a) and also specific encoding/decoding sub modules (11b-13b)
