Hyper Elliptic Curve Based Homomorphic Encryption Scheme for Cloud Data Security

Abstract

Another rising pattern in the field in PC innovation is Cloud computing. Generally, the information was kept up and controlled in one possess servers. Cloud computing is a stretchy, savvy, and affirmed conveyance stage for giving business or shopper IT benefits in overabundance of the Internet. Today, Cloud provider gives conveyance of registering as an administration. Contingent upon the administration, the colossal data is shared over the system and this tremendous measure of information is put away in the cloud service provider. Henceforth, security is a noteworthy worry for the information in the cloud. Different encryption calculations were combined for securing the information in the cloud. Yet at the same time, the information is not secure in the cloud because of different assaults on the information. Thus, another method called Homomorphic encryption is presented which is a smart thought that enables particular operations to be performed on the scrambled information. In this paper, we propose hybrid homomorphic encryption calculation for giving improved security and secrecy of the information that is put away in the cloud. The Encryption procedure is conveyed by utilizing Hyper Elliptic Curve Cryptography (HECC) calculation, which creates a key, this resultant key is sent to the cloud provider where Homomorphic multiplicative operations are combined to the scrambled key. Hence, the encoded key is put away in the cloud which can be gotten to whenever. Since the cloud supplier has the scrambled key no other individual can have the capacity to know which operation has been performed. Consequently security and confirmation is upgraded. For the best Performance and most incredible security of cloud computing, this paper proposed homomorphic hybrid encryption strategy. Both are ideal, a mix of HECC and Homomorphic encryption to hybrid calculation. Here first we are creating key from HECC cryptosystem then these private and public keys taken after by Homomorphic with the end goal of encryption/decoding, for a safe scrambled correspondence of clients in cloud.
