Abstract (en)
[origin: WO2022238644A1] The invention relates to a method for defending against an attempt to disconnect two entities corresponding to a network access point (120) and a client device (110), said method comprising, after the establishment of an initial connection between said two entities, a set of steps implemented by one or else each of said two entities: receiving (E10, E20) a set of disconnection requests (ENS_1, ENS_2), evaluating (E30, E40) at least one criterion (CRIT1_i, CRIT2_i) defined on the basis of a metric based on said set of requests or else on at least one other disconnection request received after the receipt of said set of requests, so as to allow the detection of a malicious disconnection attempt. Said method furthermore comprises, if at least one criterion is met for at least one of said two entities, a step (E50, E60), performed by at least one of said two entities, of executing a process of protecting against said malicious disconnection attempt.
