Abstract Protecting sensitive data is crucial in the age of widespread data digitalization and cloud-based services. This paper proposes a unique hybrid encryption algorithm deployed and tested over the cloud platform. The algorithm is reinforced with the robust cryptographic combination of Advanced Encryption Standard (AES) and Rivest-Shamir–Adleman (RSA). By utilizing the inherent benefits of symmetric and asymmetric encryption, the algorithm aims to improve the efficiency and security of data at rest and data being transmitted in a cloud-based environment. When tested on varied-length files and large data, the proposed algorithm encrypts the data securely and quickly. Various attacks including brute force, cryptanalysis were performed in the deployed environment to test the efficiency and effectiveness of the algorithm. It is observed that the algorithm outperformed Diffie-Hellman algorithm in terms of speed of encryption and data security with a factor of 6%. The algorithm's robustness against different security risks and its flexibility in changing cloud situations through an extensive examination is proven. The results not only highlight the hybrid approach's efficacy but also support its possible use in practical applications, therefore launching a new wave of robust cloud-based data management systems.
