Abstract:

This paper aims to develop and analyze a Secure Message Transmission System over a WiMAX (Worldwide Interoperability for Microwave Access) communication system with the implementation of the Advanced Encryption Standard (AES) encryption algorithm using AWGN communication channel. WiMAX has many potentials to be the leading communication technology, offering high-speed internet service up to the customer. The WiMAX technology standard 802-16 wireless MAN is configured as a traditional cellular network with base stations using point to multipoint architecture and can provide a service coverage of a few kilometers. However, wireless data transmission systems are not secured as other networking technologies. Many security concerns are required to secure a wireless network. Simulation is done using Matlab 7.5 simulation tool with necessary parameters for WiMAX communication system and AWGN channel. The results indicate that the shared secret key is adequate to properly hide the plain text over AWGN communication channel using AES. Leading us to believe that with necessary security measures WiMAX could provide privacy and security over a larger distance.
