Limitations Of Wired Equivalent Privacy - 2704 Words

Limitations of Wired Equivalent Privacy Presented in IAAS670 Wireless and Mobile Security By Joel Bramblett, Oluwaseun Onibudo, and Michelle Rowton Davenport University October 21, 2014 Nasser Halwani Professor Abstract The Wired Equivalent Privacy algorithm (WEP) is a method of securing IEEE 802.11 wireless internet connections. This algorithm was accepted by the IEEE (The Institute of Electrical and Electronics Engineers) in 1999 and it was subsequently used as the standard for wireless security JATIT (2012). Just over 5 years after its ratification by IEEE, the same body phased it out after some FBI personnel demonstrated how easy it was to crack (in as little as three minutes) (Cheung, 2005). This marked the entry of WPA/WPA2 (Wi-Fi Protected Access), but this is not our area of concentration in this paper. This paper opens with an introduction into the world of WEP and proceeds by concentrating on the various vulnerabilities that led to the abandonment of the WEP as a secure protocol for wireless networks. Our discussion will center on WEP limitations regarding initialization vectors and the method of encryption –RC4 vis-à  -vis the probable fixes for the vulnerabilities. We will conclude by looking at the full WEP operational picture and possible recommendations for securing wireless networks in this modern age.

Access points (base stations) can be hardware based or software based. The hardware based access point is a separate component connected to a wired Ethernet network and or server via an interface card. Software based access points can be a computer operating with software installed and is connected to a wired Ethernet network with an interface card.

Because it’s very difficult to setup wire in old and big buildings, in WLAN we can modify anything easily because of less wiring as well as the installation cost is very less as compare to wired network. The other feature for WLAN include cost- WLANs is backbone for the regular users who access to the internet every day, giving them anytime, anywhere network access.

Information access via a mobile device is plagued by low available bandwidth, poor connection maintenence, poor security, and addressing problems. Unlike their wired counterparts, design of software for mobile devices must consider resource limitation, battery power and display size. Consequently, new hardware and software techniques must be developed. For example, applications need to be highly optimized for space, in order to fit in the limited memoryRead More The Next Great Wall Essay3074 Words   |  13 Pagesother hand, did not go through such a process. Restrictions on encryption technology imported to or developed within China have been put forth. Their attempts at such control contrast what the United States considers is a denial of our rights to privacy even when addressing national security. The U.S. has acknowledged the significance of supporting free encryption policies while Chin a’s restrictions have shown they are even more limiting, unenforceable and morally wrong in how it affects its citizensRead MoreThe Wlan4915 Words   |  20 Pages However, the bandwidth limitations when using switched cellular technology are severe, and data connections generally are not tolerant of the extended drop-outs that can occur. Conversely, WLANs are generally accepted to be 1Mbps links or above (although a few drop into the 100s of Kbps), short range (100s of meters) technologies which do not need to support vehicular mobility (high speed handoffs) or wide area coverage. What they do provide is the wireless equivalent of a LAN for file sharingRead MoreA Brief Note On Companies And The Largest Ever Consumer Data Breach1712 Words   |  7 Pagesparty.

Speed is 300 Mbps, Security protocols are WEP, WPA, WPA2, Security level can be declared as high. This standard was approved in 2009. 802.11n is comparable in transmission speed to the wired standards. The maximum transmission speed of the standard 802.11n is about 5 times higher than the performance of classic Wi-Fi. The increase in the transmission speed in the IEEE 802.11n standard is achieved, firstly, due to the doubling of the channelRead MoreWireless Technology2031 Words   |  9 Pagestype with possibly differing  bandwidth  and quality-of-service requirements.
