Abstract:
Authentication with security in wireless networks may be provided. A first confirm message comprising a first send-confirm element and a first confirm element may be received. Next, an Authenticator Number Used Once (ANonce) may be generated and a second confirm message may be sent comprising the ANonce, a second send-confirm element, and a second confirm element. Then an association request may be received comprising a Supplicant Number Used Once (SNonce) and a Message Integrity Code (MIC). An association response may be sent comprising an encrypted Group Temporal Key (GTK), an encrypted Integrity Group Temporal Key (IGTK), the ANonce, and the MIC. An acknowledgment may be received comprising the MIC in an Extensible Authentication Protocol (EAP) over LAN (EAPoL) key frame and a controller port may be unblocked in response to receiving the acknowledgment.
