IEEE 802.11 MAC 프로토콜에서 전력제어관리의 프로토콜 취약점분석

다국어 초록 (Multilingual Abstract)

IEEE 802.11 wireless network is different from wired network with regard to transmission media, mobility, MAC protocol vulnerability, limited power on a battery, and so on. In order to take full advantage of mobility, the location of a station shouldn't be a constraint, including the availability of electrical power. But battery power is a limited resource. So 802.11 MAC have some power management protocols to minimize spending the power. AP can buffer frames to the station which is in sleep mode because all traffic for mobile stations must go through AP. But attacker send contaminated frames which are spoofing MAC address, association ID, BSSID to AP. AP send buffered frames to attacker. Thus attacker could intercept the frames. This paper present the interception technique of buffered frames on vulnerable 802.11 MAC protocol for power control. And we also constitute a test environment and check interaction between AP and the station to find out why it is vulnerable.
