A Novel Cryptographic Approach for Enhanced Data Security in Cloud Computing Environments Using Residue Number System and Advanced Encryption Standard

The rapid growth of cloud computing has made it an important area of study in computer science. While cloud computing offers many benefits, it also faces many challenges, including information security. To address this challenge, this paper proposes and tests a new double-layered encryption method to improve data security in the cloud. The method combines the residue number system (RNS) and the advanced encryption standard (AES) to reduce hardware complexity and improve encryption efficiency. This help address the changing landscape of security threats and computational needs that are part of cloud computing. The results show that the proposed method has the features needed to make an effective encryption algorithm for cloud computing. It combines security and speed and works better than other hybrid AES cryptographic techniques. The proposed technique was comprehensively evaluated and tested using Python Programming Language version 3.9.7, executed on a 1.4 GHz Quad-Core Intel Core ™i5 macOS processor laptop.
