A Comprehensive Approach to Ensure Secure Data Communication in Cloud Environment

computing is an Internet based development, in concept, it is a paradigm shift whereby details are abstracted from the users who no longer need knowledge of, expertise in, or control over the technology infrastructure that supports them. According to a 2008 IEEE paper, ―Cloud Computing is a paradigm in which information is permanently stored in servers on the internet and cached temporarily on clients that include desktops, entertainment centers, table computers and notebooks etc.‖ Some examples of emerging Cloud computing infrastructures are Microsoft Azure, Amazon EC2, Google App Engine, and Aneka. Cloud service providers enable users to access and use the necessary resources via the internet. To provide these resources, providers often fall back upon other providers in the cloud, hence this raises security issues in Cloud Environment as Clouds have no borders and the data can be physically located anywhere in the world. So this phenomenon raises serious issues regarding user authentication and data confidentiality. Hence it is proposed to implement a simple Data Protection framework which performs authentication, verification and encrypted data transfer, thus maintaining data confidentiality. Programming is performed using JAVA platform, Cloud environment is created using wired and wireless LAN networks. And Advanced Encryption Standard security algorithm is implemented for ensuring security framework.
