Data Protection In Clouds Using Two Stage Encryption

Cloud Computing has been an emergent technology that has opened the space for virtualization, as it provides many computational services and storage services over the Internet with the help of a browser. Cloud computing's core comprises of services like platform, infrastructure and software as a service. The unpredicted boom in cloud computing is driven by its simple economic benefit. It helps in reducing capital expenses and minimizes operating expenses. This move however, has increased a major concern about the protection of data, as against the traditional system the data is now stored online and is far easily exposed than we realize. This raises a major security issue for data protection. Many techniques for protection of data have been proposed so far. However, the best available option till date is to encrypt user data before storing it over the cloud environment and decrypting it again before handing the data back to the cloud user. In this paper, we introduce a more efficient and stronger encryption process that allows a cloud service provider to protect user data more efficiently.
