Abstract
Wired Equivalent Protocol(WEP) is the security protocol on MAC layer of WLAN, implemented by IEEE 802.11. Although widely used today, its obvious security holes are already pointed out by researchers[l]. Therefore, several new security protocols, such like Temporal Key Integrity Protocol(TKIP), Protected Extensible Authentication Protocol(PEAP), WEP2 and Synchronized Random Numbers Generator(SPRiNG) protocol, are proposed to quickly fill the gaping hole left by WEP. This paper is to analyze and compare these four protocols and then make a conclusion.
