A method and a device for maintenance filtering to process a flow of m coded incoming messages Esj each with nj Inputs/Outputs esi,j, a checksum ΣSesi,j of signatures Sesi,j, and a date dj. outgoing message Esmj is generated from each incoming message with nj Inputs/Outputs esmi,j, a checksum ΣSesmi,j of signatures Sesmi,j, and the date dj. The novel maintenance filtering device maintains at least one state of at least one Input/Output esi,j of at least one of the incoming messages Esj for a period of time Ti whatever the state of an Input/Output of an incoming message consecutive to the incoming message Esj by generating at least one outgoing message wherein the state of the ith Input/Output of the outgoing message is equal to the state of the Input/Output esi,j of incoming message Esj. The maintenance filtering device includes a calculation device, a pseudo-random generator, and a compensation table.
