SECURED COMMUNICATION IN WIRELESS NETWORKS USING MODIFIED ADVANCED ENCRYPTION STANDARD ALGORITHM

Electronics and Communication Engineering

In this work, the design and implementation of secure communication in the wireless network was carried out. The design was accomplished by using a Modified Advance Encryption Standard (MAES) algorithm and Intellij IDEA by Jetbrains. A byte rotation technique was used to modify the Advance encryption standard algorithm in order to improve security of files over a wireless network. In the work, files were encrypted such that if they fall in the hands of unauthorized users, their content remains secured because MAES was used to encrypt them. Text files of different sizes were used to test the design, and file encryption and decryption without loss in fidelity was achieved using the MAES algorithm A large number of text files of different sizes were used to test the system and the results obtained were compared with the Advanced Encryption Standard (AES) algorithm, which is also very efficient in terms of speed degree. Hence, byte rotation used to modify AES does not only improve security but equally little bit faster than AES. The research therefore recommend amongst other things the usage of MAES for securing files.
