Study of WiMAX Based Communication Channel Effects on the Ciphered Image Using MAES Algorithm

摘要

Protection of multimedia information from different types of attackers and send it over communication channels has become important for people and governments. The form of reconstructed image from an actual transmission channel is an important challenge faces the ciphering algorithms. MAES algorithm is an important modified version of AES algorithm used to cipher an image with high security level and low computation cost. This paper presents an study of Channel effects on MAES ciphering algorithm. An encrypted image by MAES is transmitted and received over WiMAX standard then check its features. Comparison between original and reconstructed versions of secret image was done. Many parameters such as visual scene, histogram analysis, correlation coefficients and entropy were used to achieve this comparison. The results of study achieved in this work proved that the ciphered algorithm is strong against WiMAX channel problems especially when the SNR of the channel increased.
