METHODS OF PROTECTING MANAGEMENT FRAMES EXCHANGED BETWEEN TWO WIRELESS EQUIPMENTS, AND OF RECEIVING AND TRANSMITTING SUCH FRAMES, COMPUTER PROGRAMS, AND DATA MEDIA CONTAINING SAID COMPUTER PROGRAMS

摘要

The management frame protection method comprises, for the first management frame (7, 8, 9, 10) sent by a first equipment and received by a second equipment, a step of inserting in said first management frame (7, 8, 9, 10) a parameter f(X₀) that is an image of a predetermined numerical value X₀ as obtained by a mathematical function f that is difficult to invert and that is known to both equipments, and for each k^th management frame (7, 8, 9, 10) sent by the first equipment and received by the second equipment: · a step of inserting in said k^th management frame (7, 8, 9, 10) a parameter f(X_k) that is the image of a numerical value X_k as obtained by the mathematical function f, and a numerical value X_k-1 that was used to determine a parameter f(X_k-1) inserted in a (k-1)^th management frame (3, 4, 5, 6); and · a step of the second equipment comparing an image of the numerical value X_k-1 as obtained by the function f as received in the k^th management frame (7, 8, 9, 10) with the parameter f(X_k-1) received in the k-1^th management frame (3, 4, 5, 6).
