Abstract:
1. A method for processing at least one data packet sent by a machine, transmitted through a second data transmission network to a first interconnection device between said second data transmission network and a first data transmission network and then through said first data transmission network to a receiving entity, the at least one data packet transmitted through a third data transmission network to a second interconnection device between said third data transmission network and said second data transmission network, said method comprising: obtaining first identification data of said first interconnection device; obtaining an identifier of a first decoding function associated with said first identification data from a decoding functions table storing a decoding function identifier in association with device identification data, said first decoding function being an inverse function of a first encoding function applied by said first interconnection device to the at least one data packet before transmission; generating a second packet by applying said decoding function to the at least one data packet; obtaining second identification data of said second interconnection device; obtaining from said decoding functions table an identifier of a second decoding function associated with said second identification data, said second decoding function being an inverse function of a second encoding function applied by said second interconnection device to the at least one data packet encoded in accordance with the first encoding function before transmission; and generating a third packet by applying said second decoding function to the second packet.
