Security Research on WEP of WLAN
نویسندگان
چکیده
Wires Equivalent Privacy (WEP) is used to improve the security of wireless LAN (WLAN). By analyzing the weaknesses of WEP and RC4, we design a simulative platform including software and hardware to crack WEP keys. The results show that the WLAN based on WEP is insecure. At last we give some improvements to enhance the WLAN security.

Implementation of Wlan Wep Protocol by Rc4 Algorithm in Vhdl
The WLAN is a network that utilizes radio frequency technology. The security of wireless data stream becomes particularly prominent. The WLAN uses RC4 stream encryption algorithm of the WEP protocol to enhance its Security.WEP itself also has fatal Security flaws, tampering with the data for a variety of active attacks. In essence, the problem is not in RC4 itself but in the way to generate the...
متن کاملOn the Impact of Security on the Performance of WLANs
This paper investigates the impact of security on the performance of WLAN. More specifically, it analyzes the impact of different implementations of encryption techniques used by two security protocols, namely Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) on the throughput over WLAN IEEE 802.11g. This paper also addresses the different issues related to the security protocols ...

The common trend in the new century has been for wireless computer networks to replace wired ones, due to increased mobility and greater convenience. Since the wireless network is simply broadcasting a signal, which anyone can connect to this Wireless Local Area Network (WLAN) and receive the signal with the proper equipment. Thus, these types of networks are fundamentally less secure than the ...
متن کاملWireless Security: WPA Vs WAPI, should we be worried?
The IEEE 802.11 standard includes an optional encryption capability, the Wired Equivalent Privacy (WEP) however, WEP is vulnerable to attack and can easily be broken, therefore WEP was recently temporarily supplemented with Wi-Fi Protected Access (WPA) which offers improvements over WEP while a newer, more secure protocol 802.11i is developed. However, China has now introduced a new security pr...
متن کاملEvolution of Wireless LAN Security Standards
As wireless LANs (WLANs) become ubiquitous, the issue of network security in the wireless domain becomes one of crucial interest. In response to security concerns, the IEEE standard 802.11 proposed a protocol known as Wired Equivalent Privacy (WEP). However, the discovery of serious loopholes in WEP had a negative impact on the deployment of WLANs for corporate networks, and possibly on the gro...
