| description | Cloud has become one of the most widely used technologies to store data due to its availability, flexibility, and low cost. At the same time, the security, integrity, and privacy of data that needs to be stored on the cloud is the primary threat for cloud deployment. However, the increase in cloud utilization often results in the creation of a multi-user cloud environment, which requires its owners to manage and monitor the data more effectively. The security of information faces an additional threat, which is related to the increasing number of users and owners who deal with the data stored on the cloud. Many researchers have developed several frameworks and algorithms to address the security issues of the cloud environment. In the present work, a novel algorithm is proposed with the integration of Ciphertext Policy-Identity Attribute-based Encryption (CP-IDABE) and the Rivest–Shamir–Adelman (RSA) algorithm for securing the cloud. Both the owners and users are provided with the public and distinct secret keys that are generated by the Automated Certificate Authority (ACA). The attribute policy differentiates between the user and owner for accessing the cloud data. The proposed RSA-CP-IDABE algorithm also prevents the Man in the Middle (MITM) attack effectively. The performance of the proposed algorithm is evaluated for its time used for encryption, decryption, and execution for varying sizes of data. The obtained results are compared with the existing framework to show its effectiveness. The proposed algorithm can be enhanced with the revocation of privileges in the future. |
