“…Public verification for key can also be done using [3] Robert secretsharing scheme where knowing both global keys and (n−1) shares would not retrieve us the plain text that was being shared. In RSA algorithm [10], each piece of key is in parts such that it cannot be computed without the secret or private key owned with the owner itself, and the encryption cannot be executed if its exceeds the threshold value (t).…”

Cloud computing has become an emerging model of IT industry as it can be accessed anywhere in the world on a pay-per-use basic. But, one major problem it is facing in today’s challenging world is the security issues. Whenever the data is transferred through different connected networks, the threat is there for the users, that their data might get leaked from outsiders or an unauthorized people.In this paper we propose the solution for the above mentioned problem. We go through the cryptographic techniques by combining the two messages into an encrypted data and then sending it to the destination. We also propose a new method of how to exchange the keys and how the keys get interact at the user and system level.

“…In this section describing the solutions that have been proposed in [6], authors have considered that the applications involving a number of servers in the cloud that go through a sequence of online periods where the servers communicate, separated by offline periods where the servers are idle. During the offline periods, servers need to securely store sensitive information such as cryptographic keys.…”

“…In [6] proposes PKI based cryptography scheme for cloud storage. The scheme has the following advantages: First it can ensures the users have the identity they claim in the virtual cloud storage world, Second it secures the data during its entire life cycle the whole process doesn't reveal the clear data to any third party including the cloud provider, Third it offers controlled data access and sharing among users, so that unauthorized users or untrusted servers cant access or search over data without data owners authorization.…”

Abstract-Cloud computing is going to be very famous technology in IT enterprises. For an enterprise, the data stored is huge and it is very precious. All tasks are performed through networks. Hence, it becomes very important to have the secured use of data. In cloud computing, the most important concerns of security are data security and privacy. And also flexible and scalable, fine grained access control must be maintained in the cloud systems. For access control, being one of the classic research topics, many schemes have been proposed and implemented. There are policy based schemes have been proposed. In this paper, we are going to explore various schemes for encryption that consist of Attribute based encryption (ABE) and its types CP-ABE. Further discussion consists of improvement in CP-ABE to CP-ASBE and to HASBE. A comparison table has been included for comparative study of these techniques. In this project, we propose a framework for efficient and privacy-preserving outsourced cloud using CP-ABE technique. Our proposed technique is designed to allow users to outsource their own data to cloud server for secure processing. Using CP-ABE, a user can securely outsource the storing and processing of data to a cloud server without compromising the security of the (original) data and the computed results. More specifically, we present a cipher policy attribute based encryption with RSA key distribution, the core cryptographic primitive, to reduce the private key exposure risk in data processing.
