Enhancing the Process of AES: A Lightweight Cryptography Algorithm AES for Ad-hoc Environments

Ad hoc networks have become more widespread and important because they support mobility can be used in different situations some difficult areas such as rescue missions, military, vehicular communications. Security is stated among the most significant challenges facing Hoc due to its characteristic features topology dynamicity, lack of infrastructure centralization, open architecture. work on battery power, this kind tend consume power time process data memory resources through encryption, eventually requiring a higher amount time. Therefore, an AES lightweight algorithm proposed, which one complicated encryption algorithms. This will modified improve security well reduce energy consumed comparison with original algorithm. The enhanced version based outputs sub byte shift row, addition exclusive X-OR operator between them, whereby output added round key layer. results confirm that efficient, accurate, robust against multiple types attacks related ad networks.
