First section is intro in WiFi technology and terminology. The second section shows the security architectures and algorithms used in WiFi networks. Both important mechanisms: encryption/decryption as well as authentication is analyzed within simple IEEE 802.11 approach in section three and four. The architectures such as WPA or WPA2 are not subject of this paper.
