Current trends in the security of Wi-Fi IEEE 802.11 networks
Blažek, Ondřej ; Škorpil, Vladislav (referee) ; Endrle, Pavel (advisor)
This work describes security options of 802.11 standard. Principle of WEP algorithm is described here, problem with his inicialization vector which leads to a statistical attack and revelation of his secret key. Moreover other principles of algorithms such as WPA, WPA2 are explained here along with a practical demonstration of bruteforce attack in a practical part of the thesis. Also the influence of encryption on network throughput is tested here using tool Iperf.

Attacks on Standard 802.11
Burian, Vojtěch ; Horváth, Tomáš (referee) ; Novotný, Bohumil (advisor)
Thesis is concerned about standard 802.11 especially wireless network security in historical and in current way. First part is focused on WEP secured wireless network problematics. Consequently, in different point of view we are focused on network security which was developed recently, for example WPA and WPA2 security. It will be marked the basic functioning and brief overview of standard 802.11, introduction to the known attacks on wireless network security and also indicate the main mistakes. Many older devices have only WEP security. Therefore, in this thesis is designed better and more coherent system of security of the WEP protocol. As well modern methods of security WPA and WPA2 are included. Second part is focused on the simulation of attack on security networks. In this part the problematic with beaking security WEP, WPA and WPA2 is discussed.
