Ensuring data storage security in cloud computing based on hybrid encryption schemes

Cloud computing is a latest computational framework that provides different types of business model for organization to adopt IT without any front-end investment. It has often associated with virtualized infrastructure or hardware on demand, utility computing, IT outsourcing, platform and software as service and many other things. It also provides on demand computational infrastructure which has the power to reduce the cost to build the IT based services. Storage where users can keep their data as per the requirement, is one of the important services of cloud computing. 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 based on Hybrid Encryption Schemes which can encrypt 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.
