Abstract:
1. A method of transmitting data in a plurality of sets of data packets from a first terminal to a second terminal in a telecommunications network adapted to transmit data in packets, the method comprising: a) receiving in the first terminal and the second terminal a selection rule and a secret list of transmission frequencies from said telecommunications network; b) selecting in the first and second terminals transmission frequencies from the secret list of transmission frequencies using said selection rule; and c) transmitting the plurality of sets of data packets from the first terminal to the second terminal at respective selected transmission frequencies, wherein said secret list of transmission frequencies is generated in accordance with a transmission frequency list allocation rule from a list of available frequencies received from the first and second terminals and collected by said telecommunications network, and wherein the number of frequencies contained in said list of available frequencies with respect to said first and second terminals is equal to the product of the number of frequencies contained in said list of transmission frequencies common to said first and second terminals generated according to the allocation rule and a specific number determined as a function of a level of confidentiality required for transmitting said sets of data packets.
