Providing More Security to Data Stored in Multi-Cloud Environment Using Encryption and Decryption Techniques

Abstract: Because multi-cloud computing may lower service costs in a multi-cloud environment, it is an emergent idea that has become the newest subject of study. Because there is a lack of centralized management and diverse technologies, managing user access across numerous cloud systems is challenging. For uniform rules, native controls from different multicloud providers are insufficient. A centralized framework that unifies security and access controls across all platforms is necessary for a successful multi-cloud security approach. The RSA algorithm is the method used to improve data security. Time complexity, space complexity, and throughput are the three main factors used to evaluate security performance. Research projects involve encrypting data with RSA to restrict access to certain users and thwart unwanted access. The information is multi-cloud stored, encrypted, and released upon user.
