Confidentiality and Storage of Data in Cloud Environment

摘要

In this paper, we provide a secure storage of data in the cloud server using Identity-Based Encryption. Where the data owner shares the stored data with the cloud users on the basics of pay-as-you-use principle. The cloud user request for the encrypted data, stored on the cloud server's database (by applying encryption on keyword) and the server verifies the request by performing test on encrypted data. So, that illegal users or unauthorized servers cannot attack on the data.
