Ultimate Cloud

چکیده
One of the supreme perplexing problems of cloud service provisioning is to motivate users to believe and to trust the security of cloud service and upstream their sensitive data. Even though cloud service providers can say that their services are heavily protected by extravagant encryption methodologies, modern cloud systems still cannot convince the users that even if the cloud servers are exploited, the data is still strongly protected. This study proposes Ultimate Cloud, a scheme which uses all formidable technologies culminated together to form a most secure mechanism for cloud data fortification, in every way that is possible. Ultimate Cloud employs AES, RSA and indirectly encrypts users’ data by their public keys, but stores their private keys on nothing; instead, they are stored on any mobile devices and accessible via 2-dimensional barcode images such as QR codes. And they are employed to decrypt users’ sensitive data. In this way, users’ data are securely protected even if the cloud servers are compromised. Also, Ultimate Cloud provides users with the knowledge of managing private keys by storing the keys into mobile devices and displaying them via QR codes. Moreover, three Modules exist such as: personal, home and enterprise level scenarios are proposed to present the achievability of Ultimate Cloud. In addition, a classified structure is designed for key randomization and data sharing in the suggested structure.
