发明名称 PROCEDE DE SECURISATION DE MESSAGES TRANSMIS PAR UN TERMINAL EMETTEUR A UN TERMINAL RECEPTEUR DISTANT.
摘要 <p>The invention relates to a method of securing an integer number n greater than or equal to 1 of messages MUi (i = 1 to n) transmitted by a sender terminal to a receiver terminal in which, prior to the sending, by the sender terminal, a- generating an ordered sequence comprising N data blocks Bj (j = 1 to N), N being an integer greater than or equal to n, b- for each message MUi (i = 1 to n), calculating a position pi in said ordered sequence of N blocks by means of a function F, c- encapsulating each message MUi (i = 1 to n) in the block Bj situated in position pi, and, d- transmitting the ordered sequence comprising the messages MUi to said receiver terminal, and on reception, by the receiver terminal, e- recalculating the positions pi (i = 1 to n) of the blocks Bj encapsulating the messages MUi by means of said function F, f- extracting the blocks Bj occupying the positions pi (i = 1 to n) of the ordered sequence received, g- extracting the messages MUi encapsulated in said blocks Bj.</p>
