Description
Summary:Cloud computing is a broad and diverse phenomenon. Users are allowed to store large amount of data on cloud storage for future use. The various security issues related to data security, privacy, confidentiality, integrity and authentication needs to be addressed. Most of the cloud service provider stores the data in plaintext format and user need to use their own encryption algorithm to secure their data if required. The data needs to be decrypted whenever it is to be processed. This paper focuses on storing data on the cloud in the encrypted format using fully homomorphic encryption. The data is stored in DynamoDB of Amazon Web Service (AWS) public cloud. User's computation is performed on encrypted data in public cloud. When results are required they can be downloaded on client machine. In this scenario users data is never stored in plaintext on public cloud.
