Abstract
Many users are using IEEE 802.11 WLAN technology for accessing Internet in hotspot and enterprise environments. However, in spite of progress of network throughput, the users sometimes feel inconvenience about the long initial access time for secure authentication, link layer key exchange and IP address setup. In order to solve this problem, IEEE 802.11ai adopts the fast initial link setup (FILS) with EAP reauthentication protocol (ERP). With FILS, the initial access time including authentication can be reduced when user connect a wireless network again after the first connection and authentication. Meanwhile, there are security threats in IEEE 802.11 WLAN technology such as eavesdropping, rogue access point attack, denial of service, etc. Especially, denial of service attack is possible using the essential flaw of IEEE 802.11 or 802.1X protocol. Similarly, this type of attack is also possible in FILS process. In this paper, we introduce three examples of denial of service attacks in FILS and propose the countermeasure against these attacks.
