Method for defending attempt to disconnect two entities and associated system

The invention relates to a method for defending against an attempt to disconnect between two entities corresponding to a network access point (120) and a client device (110), said method comprising, after establishing an initial connection between said two entities, a set of steps implemented by one or each of said two entities: receiving (E10, E12, E12, E14); e20) a set of disconnection requests (ENS1, ENS2), evaluating (E30, E40) at least one criterion (CRIT1i, CRIT2i) defined according to a metric on the basis of the set of requests or on the basis of at least one other disconnection request received after receiving the set of requests, in order to allow detection of malicious disconnection attempts. The method further comprises a step (E50, E60) of performing, by at least one of the two entities, a process of preventing the malicious disconnection attempt if at least one criterion is met for at least one of the two entities. 本发明涉及一种用于防御与网络接入点(120)和客户端设备(110)相对应的两个实体之间的断开连接尝试的方法，所述方法包括，在所述两个实体之间建立初始连接之后，由所
