Abstract

The invention relates to a roaming method for a station (A') moving from a first access point (B1) to a second access point (B') in a wireless network, said method being characterised in that it comprises: a step (6A') of receiving, from the first access point (B'), data comprising a master key (PMK) encrypted by means of a secret (K) known at least to an authentication server (C), the first access point (B') and the second access point (B'), wherein said master key (PMK) results from a negotiation between the authentication server (C) and the station (A') and was received by the first access point (B') from the authentication server; and a step (7A') of sending the encrypted master key (PMK) to the second access point.
