The filter module includes a unit for generating a main table for each message, representing a tree of the fields of the payload of the message according to a set of levels related to the communication protocol, and a unit for calculating, for each message, a dictionary table and at least one auxiliary table from among first, second and third auxiliary tables, the filter module using the at least one auxiliary table for filtering the message.
