Abstract
Wireless network technology’s widely used brings the web’s users huge convenience and flexibility, and also brings great challenges for the security of network.This paper introduces the MAC address authentication, Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WiFi Protected Access 2 (WPA2) and 802.1X and so on, giving priority to analysing their pros and cons. A new model will be used to cope with the security issues of WIFI based on it.
Highlights
WIFI means wireless local area network based on IEEE802.11b
Comparing with the Bluetooth technology and others, the high-speed of WiFi technology can meet the requirements of the development of the information-based society
Wired Equivalent Privacy (WEP)[4] is a security protocol, which can be applied to wireless local area network (WLAN) of 802.11b standard
Summary
WIFI means wireless local area network based on IEEE802.11b. As a new generation of wireless network technology, WIFI can get ethernet network performance, rate and availability for wireless network users, and seamlessly combine variety technology of LAN. The number of wireless AP is growing rapidly, on account of wireless network’s convenience and efficiency can make it spread quickly[1]. Open nature of the wireless network determines it is more vulnerable than wired network in safety. When we enjoy the convenience and flexible features which the wireless network brings, it will be of great use to take technical measures to improve security
