Multi-dimensional security in cloud using Encryption & Authentication

Abstract

In today’s world where every dimension of human life is witnessing new developments almost every day, the
traditional computing is also improving exponentially. One of the most revolutionary improvement is the conception of
Cloud computing. Cloud computing systems are the need to time and way to go forward with technological improvements
in world of IT. It has a wider variety of solutions for various IT user/developer communities. It not only offers a high
degree of mobility, flexibility to its user, it provides a hassle free computing environment as well.
However as with every distributed computing platform, it is also not un-touched with a set of concerns, biggest of which is
security and data privacy. In order to provide a secure cloud environment where every user has its own data privacy and
integrity intact, cloud system have to be absolutely security complaint and able to overcome any kind of intrusion or
malicious activity against them.
As the cloud computing is gaining maturity, there have been widespread advancements in securing cloud systems, by
providing various security measures. Various organizations, researchers and authors around the world have come up with
distinct ideas to secure cloud systems and have benefitted the world with their ideas.
In this paper we have provided an overview of cloud computing systems, common security issues, and their solutions and
have subsequently proposed a solution for providing multi-dimensional security for cloud system, up to a certain extent
the proposed work also caters to the need of cloud system availability. We have used AES and RSA as encryption
techniques and CHAP authentication techniques to achieve some of the security goals
