A FRAMEWORK TO ENSURE SECURED DATA ACCESS IN CLOUD COMPUTING

Computer Science & Engineering

Cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics and more—over the Internet (“the cloud”). Cloud computing is a next generation technology for IT companies. It has different characteristics like On-demand self-service, Rapid elasticity, Resource pooling, 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 provides various types of services over the internet. Some of the services provided by the cloud are Infrastructure-as-a-service (IaaS), Software as a service (SaaS) etc. With IaaS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems from a cloud provider on a pay-as-you-go basis, 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 & accessing 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 will generate each user a unique access code basing on some parameters and allow them 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.
