INFUSION OF WIRELESS EQUIVALENT PROTOCOL (WEP) TO DATA TRANSMISSION WIRELESSLY

ABSTRACT

Wireless Equivalent Protocol (WEP) mechanism to provide confidentiality and integrity of traffic in the WLAN and is used at the two lowest layers of the Open Systems Interconnect (OSI) reference model, data link and physical layers; thereby, it does not offer end-to-end security. The aim of the study is to designate a system that will infuse a Wireless Equivalent Protocol (WEP) to Data Transmission Wirelessly. In achieving this aim, the following specific objectives were laid out to design and develop a system that will: present an analysis of the most efficient and used security protocols implemented to overcome the security problem of Wireless Equivalent Protocol (WEP), determine the nature of Wireless Equivalent Protocol (WEP) that supports Wireless Data Transmission, establish the connection of Wireless Equivalent Protocol (WEP) in application software system, and determine the type of Wireless Equivalent Protocol (WEP) in application software system. The methodology adopted in this study is the structured system analysis and design methodology (SSADM) which is a technical approach for analyzing and designing an application or system by applying object throughout the software development process. The programming language used is HTML, CSS, JAVASCRIPT, PHP, SQL and JQUERY. The reason why web programming languages was used is because, it is platform independent and it is a web based application. The study will provide a theoretical and conceptual appraisal of Infusion of Wireless Equivalent Protocol (WEP) to Data Transmission Wirelessly and will serve a reference point of information to IT consultants and professionals. Finally, the study will contribute to the body of existing literature and knowledge in this field of study and provide a basis for further research. The expected result is a Wireless Equivalent Protocol (WEP) that will support wireless Data Transmission of an application software.

Others are Significance of the study, Scope of work, Limitations of the Study and Definition of technical terms.

1.2 Background of Study

The WEP protocol was introduced in 1997 but was plagued by several security issues. Standards bodies began discouraging its use in the early 2000s, as more effective standards were introduced. WEP attempted to limit access to wireless network data in the same way wired local area networks (LANs) protect data. Users with physical access to the network access points are the only ones with access to wired networks. Wireless networks like Wi-Fi depend on encryption protocols like WEP to prevent unauthorized access to network data (Techtarget, 2021).

Physical security mechanisms protect a wired LAN to some degree. For example, controlled access to a building prevents outsiders from walking in and plugging their devices into the LAN. Outsiders can gain access to WLANs via the radio waves that connect to the network (Techtarget, 2021).

The Wired Equivalent Privacy protocol adds security similar to a wired network's physical security by encrypting data transmitted over the WLAN. Data encryption protects the vulnerable wireless link between clients and access points. After WEP secures wireless data transmissions, other LAN security mechanisms can ensure privacy and data confidentiality. These include password protection, end-to-end encryption, virtual private networks and authentication. These weaknesses doomed WEP. Most standards bodies deprecated the protocol soon after the Wi-Fi Protected Access (WPA) protocol became available in 2003 (Techtarget, 2021).

The challenges encountered that led to the execution of the research work is that, the size of Initialization Vector (IV) is short and can be reused, Authentication related issue which uses one way authentication, Lack of Key Management, same keys is used for longer duration, No session key is established during authentication, No replay protection, Attacker can easily crack the key and can manipulate the data, Flooding cause denial of service attack and Easy forging of authentication message.
