HYBRID CRYPTO SYSTEM USING HOMOMORPHIC ENCRYPTION AND ELLIPTIC CURVE CRYPTOGRAPHY

Abstract
Providing security and privacy for the cloud data is one of the most difficult task in recent days. The privacy of the sensitive information ought to be protecting from the unauthorized access for enhancing its security. Security is provided using traditional encryption and decryption process. One of the drawbacks of the traditional algorithm is that it has increased computational complexity, time consumption, and reduced security. We proposed a scheme in this the original data get encrypted into two different values. Using Elliptical curve cryptography (ECC) and Homomorphic are combined to provide encryption. The data in each slice can be encrypted by using different cryptographic algorithms and encryption key before storing them in the Cloud. The objective of this technique is to store data in a proper secure and safe manner in order to avoid intrusions and data attacks meanwhile it will reduce the cost and time to store the encrypted data in the Cloud Storage.
