Recent computing model that has become important is known as cloud computing which has various services like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) and Mining as a Service (MaaS). Widely used service among them is the storage service. When a company outsources its data to cloud and the data owners are maintained in the form of groups and members, it is essential to have secure mechanisms in place as the groups are very dynamic. Secure and scalable access to the data by data owners is very important in this context. Every member in a group is able to access his data and he is treated as owner to that data. This member can switch to different group when he moves to other team in future. This way there are instances in which group members move groups and the change dynamics are more. In this scenario it is challenging job to maintain groups and share data in privacy preserving fashion. Recently Recently Liu et al. proposed a scheme for secure multi-owner data sharing. In this paper we implemented an application that simulates the environment where groups and members are dynamically managed with security aspects fulfilled. The empirical results reveal that the application is useful and can be explored to use in real cloud.

Abstract:As cloud computing becomes popular, more and more sensitive information are being centralized into the cloud nowadays. For the protection of data privacy, sensitive data usually have to be encrypted before outsourcing, which makes effective data utilization a very challenging task because all the data which we outsource are in encrypted format. In this paper, we have discussed a few approaches for sharing data on cloud with minimal usage of key. We also discuss few data searching technique over encrypted data. While enjoying the advantage and convenience of cloud storage for data sharing, users are becoming more worried about careless leak of data in the cloud. To address this problem we studied various leakage models.

“…However, it also poses a significant risk to the confidentiality of those stored files. To preserve data privacy, a basic solution is to encrypt data files, and then upload the encrypted data into the cloud [6]. Cloud computing relies on large data centres consisting of thousands of servers and all application processing and resources are centralized in data centres.…”

Cloud computing is a popular subject across the IT industry, but many risks associated with this relatively new delivery model is not yet fully understood. Cloud computing is an budding information technology of data storage, of local networks (infrastructure) as well as software and has its advantages of scalability, reliability, high performance and comparatively low cost feasible solution contrast to committed infrastructures. Here, initially the data owner will encrypt the searchable index with ElGamal cryptosystem utilizing Hyper Elliptical Curve Cryptography for double encryption. The ElGamal cryptosystem is utilized for security analysis where in sharing of multiple keys between two parties are performed aiming for better security. The random integer selection in the ElGamal cryptosystem is modified based on optimization process using Modified cuckoo search (MCS). Further Hyper elliptical curve cryptography is incorporated with ElGamal cryptosystem which is utilized for encryption and decryption. Also, the hyper elliptic curve cryptography is modified using auxiliary input in the divisor calculation in order to improve security. For selecting keys, we have used Gravitational search algorithm (GSO). The retrieval process will take a two-round communication between the cloud server and the data user. The experimental results shown that, the recommended technique attains minimum storage cost and minimum computation time when compared to the existing technique.
