Abstract:

Cloud is a new growing field in the present information age used in internet that provides computing resources as a service over online. The third generation network move towards Big data, Semantic web and Cloud technology. Cloud provides various services over online where people can store, process and retrieve data from it. During the data transmission via public cloud, security is the most important concern. Security using certificate is a cost effective and time consuming task in the cloud environment. To address the limitations, a mediated certificate-less encryption scheme without pairing operation is proposed for securely sharing sensitive information in public clouds using RSA algorithm. In this approach multiple users can access the information at the same time. Here, the encrypted file send to client and the client will decrypt the encrypted file using file key. The proposed method performs better compared with existing certificate based security algorithms.
