Secure Wireless Data Propagation Using Simulation of Li-Fi Technology

The purpose of this research was to simulate a light-fidelity enabled barricade hotspot that could help address the security for information in transit in wireless networks. These networks provide an efficient means of connecting network devices. This is because they are fast, cost effective, flexible and easy to use. However, their usage is hindered by a number of challenges, owing to the fact that the physical connections between devices are replaced by logical associations. This means that anybody with a radio detector can receive these signals. Moreover, the data propagation in wireless environment is broadcast in nature and hence propagations can be overheard by anyone within a given range. To address these challenges, authentication protocols have been developed to deter any illicit access to these networks. They include Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). Wi-Fi Protected Access version 2 (WPA2) is the later version of WPA. However, these protocols have been shown to be easily compromised. This necessitates the development of more secure mechanisms for protecting the information in transit.
