Abstract

The invention relates to a method for securing a bidirectional communication channel between at least one source network (N1) and one destination network (N3) via a transit network (N2), the level of security of which is lower than that of the source and destination networks. The method includes the following steps during the transmission of first data from the source network (N1) to the transit network (N2) and to the destination network (N3) via the transit network (N2): implementing a filter (48) for said data, which includes applying (50, 52) an analysis filter to said data in order to prevent the creation of a hidden communication channel; transmitting (76) said filtered data to the transit network (N2); duplicating (46) said data; cryptographically protecting (42) said duplicated data; and transmitting (44) said protected data to the destination network (N3). Said filtered data are not transmitted by the transit network (N2) to the destination network (N3).
