We can say that we are surrounded by the computing world from every nook and corner. Cloud Computing is deemed as the most fundamentally changing phenomenon happening in Information Technology. But with great perks, comes great challenges as well, especially in the field of data security and privacy protection. The Cloud Service Providers take over chunks of private data from users for providing better functionalities. But for the sake of privacy and protection, this sensitive data should be encrypted and then outsourced to the cloud consoles. Since traditional cloud computing is performed on plaintext, many encryption algorithms were applied in the cloud for security purposes and ‘encrypted’ data was stored in the cloud from then on. This change gives fruition to a new type of encryption technique called Homomorphic Encryption. Primarily, the paper will focus on a subtype of Homomorphic Encryption called Fully Homomorphic Encryption. The objective of the paper is to propose a method to convert the sequentially processing Fully Homomorphic Encryption into parallel processing Fully Homomorphic Encryption using a Parallel Computing concept called Partitioning and thereby producing a better performing Fully Homomorphic Encryption.
