A Novel Approach for Enhancing Advanced Encryption Standard Performance and Cryptographic Resilience

—Advanced Encryption Standard (AES) encrypts data in blocks of sixteen bytes to secure confidential data stored in the cloud. For cloud-based systems, enhancements in existing encryption techniques are necessary as the nature of cyber threats evolves and computational speed becomes increasingly critical. This study presents an enhanced design of AES that substitutes two special operations, Byte Transformation and Bits Permuted Bytes, with the conventional S-Box operation to improve the speed and security of the encryption method. The suggested round structure in the new approach of AES, which preserves the original data block size, consists of the following operations: Byte Transformation, Shift Rows, Bits Permuted Bytes, Add Round Key, and Mix Columns. The analysis of the strict avalanche effect, correlation coefficient, entropy, execution time, and throughput outcomes confirms that the developed scheme improves the security and processing speed.
