A framework to ensure data storage security in cloud computing

Cloud computing is a future generation technology for IT enterprise. It has different characteristics like virtualization, multi-user, scalability and many more. It also provides on demand computational infrastructure which has the power to reduce the cost to build the IT based services. It can provide deferent types of service over the internet. One of the important services is provided by the cloud is storage where users can keep their data as per the requirement. So, it is a challenging issue for the user, as all the data are stored in some inter-connected resource pool but this resource pool are situated over different places of the world. An unauthorized users may be accessed this data through virtual machines. So, it is a very dark side of cloud data storage, this insecurity creates a big problem for users. Therefore cloud computing data security is a major problem. In order to solve the data security in cloud computing, we have proposed a new framework and an Encryption Schemes which encrypt the data and retrieve the data efficiently. The performance evaluation and validation of the proposed model is carried out and the result of performance analysis shown that our architecture are feasible, scalable and efficient.
