Fully Homomorphic Encryption (Fhe) Scheme For Secure Data Sharing In Cloud Storage

Cloud computing is an internet based independence, scalability, elasticity, ubiquitous network access, resource pooling and pay Cloud storage is nowadays very popular storage system. Cloud storage is storing of data storage which is maintained by third party. Cloud storage is saving of digital data in logical pool and physical storage spans multiple servers which are manage by third party. Third party is responsible for keeping data available and accessible and physical environment should be protected and running at all time. Instead of storing data to the hard drive or any other local storage, we save data to remote storage which is accessible from anywhere and anytime. It reduces efforts of c can access information from any computer through internet which omitted limitation of accessing information from same computer where it is stored. While considering data privacy, we cannot r unexpected privilege escalation will expose all data. Solution is to encrypt data before uploading to the server with user’s own key. Data sharing is again important functionality of cloud storage, be from anywhere and anytime to anyone. For example, organization may grant permission to access part of sensitive data to their employees. But challengi user can download the encrypted data from storage, decrypt that data and send it to share with others, but it loses the importance of cloud storage. 10(12) July 2016, Pages: 220-223
