Abstract : Cloud computing is one of today's most hotly debated research areas because of its capacity to cut computing costs while simultaneously boosting computing service scalability and flexibility. A major advantage of cloud computing is that users can access shared resources such as software and information whenever and wherever they need it. Cloud computing is now being used in a wide variety of settings, including the military, hospitals, industry, and educational institutions, to store massive amounts of data. The data or information can be retrieved from the cloud at the request of the client. Information can be classed as private, public, or sensitive and all cloud-based information is stored elsewhere. For confidential and personal data, third-party cloud providers are always difficult to trust. Even the cloud industry's biggest players agree that security is a shared duty between the enterprise and the customer. As a result, from the perspective of the client, information stored in the cloud should be encrypted thoroughly to ensure that it cannot be read by any other user. So many difficulties arise when data is stored in the cloud, including the security of that data. Many algorithms have been devised to address these problems. The use of cryptographic techniques in this study helps to alleviate security concerns. For data security, cryptography techniques are becoming more prevalent. Asymmetric Key Cryptography with Related Key Set (AKC-RKS) technique is used in this paper to give novel safety mechanisms. The proposed model is compared with the traditional encryption techniques and the results show that the data security levels of the proposed model is high.
