Implementasi KRACK dan KRACK Detector terhadap Wpa_Supplicant pada Perangkat Android dan Linux Ubuntu

Nowadays WiFi services is available in many public places to accesses the information. Most of use Wifi Protected Access 2 (WPA2) security. This protocol uses a 4-way handshake mechanism for authentication process, but there weakness by using that possible re-install key (KRACK). can be used attackers hold up communications so enter network. study, KRACK analysis was carried out on wpa_supplicant Android and Linux Ubuntu which connected WPA2 security know weaknesses. The doing user's device connecting Rogue AP generated Vanhoef script. dangerous line compared normal line. Analyzing attacks handshakes, this research create implementation Detector result detection will get characteristics. information getting from prevent disadvantages coming attacks. validation Wireshark make sure third massage sends show threat attack.
