Enhancing Performance Through Dynamic AES Round Keys and Adaptive Data Shifting Techniques

الملخص

The query discusses two encryption methods: standard AES (acting as the control group) and a new hybrid encryption algorithm (the experimental group). Symmetric encryption, such as AES, uses a private key for both encryption and decryption, applying multiple constants and iterations throughout the process. The study proposes modifications to the AES algorithm by omitting certain steps—specifically, the substitution and mixcolumn processes—while still utilizing a single key derived from a random primary key. This approach is accompanied by dynamic data displacement to bolster security and improve execution time.

The research further indicates that traditional encryption methods struggle to find a balance between maintaining strong security, operational efficiency, and resistance to various forms of attacks. In the experiments conducted, the hybrid encryption algorithm demonstrated improved encryption and decryption times across different file sizes, showcasing its competitive edge over standard AES while ensuring data security against brute force attack testing.
