Cloud computing revolutionizes the way businesses are stored and managed, and ensures robust security measures. This paper explores the use of Rivest-Shamir-Adleman (RSA) and the Magic Rectangle Generating Algorithm (MRGA) to enhance security in cloud environments. This highlights the growing significance of cloud computing and the need for effective security measures. It then introduces RSA and MRGA as cryptographic algorithms with their unique strengths and applications. It further delves into the benefits of using RSA and MRGA for data protection, key management, authentication, and identity management in cloud environments. The potential of these algorithms to address security challenges in the cloud and improve the overall data security is discussed. Additionally, the abstract acknowledges the limitations and considerations associated with the implementation of the RSA and MRGA. This emphasizes the importance of this research in enhancing cloud security and provides insights into the potential of RSA and MRGA as security measures in the cloud.
