Abstract

The paper discuss the Wireless LAN 802.11b network security. WLAN security mechanisms including the comparisons of SSIDs, MAC address filtering and the WEP key encryption. based on these authentication methods, etc. By analyzing the weaknesses of WEP and RC4, a simulative platform of software and hardware is designed to crack WEP key. Experiments show that WEP Key can be cracked including SSID enumeration, MAC address spoofing and WEP key cracking by FMS Attack. The paper propose some solutions for Wireless LAN 802.11b network security, for example, WEP key hashing, Dynamic WEP keys, Initialization Vector changes and Message Integrity Check.
