Securing Cloud Computing Environment with the help of Fully Homomorphic Encryption

Abstract

Abstract
Since its inception, cloud computing has faced a number of challenges, like data migration, adoption of new policies etc. but the most challenging and important among them has been the security and risk issues related to it. Cloud computing provides a user, the provision to use various computing resources over the internet on a leased basis. This new model of computing has gained its popularity among various organizations and individuals due to its cost effectiveness and versatile features. But as it is common to any other computing infrastructure, cloud computing environment is also prone to security threats, may be up to a larger extent than traditional computing, which is hindering its growth. Using fully homomorphic schemes, as proposed in this paper, it would be possible for a user to store their data in the cloud in an encrypted form and perform some specific computations on the encrypted data, without the cloud server’s knowledge about the data and computations at all. Hence it will help the cloud service providers to develop a secured cloud infrastructure and build trust among the users.
