A hybrid multilevel authentication scheme for private cloud environment

Abstract

Cloud Computing is the ubiquitous model of a shared pool of configurable computing resources. This paper proposes a multilevel authentication technique for use in Private Cloud network. Authentication of User is a challenging issue due to increasing security threats as it acts as the first defence against attackers. Whole authentication control lies in the server Side so Single-tier authentication is not enough to overcome these problems. We come up with a novel authentication mechanism, called Hybrid Multilevel Authentication, which provides the security against the insider attacks and virtualization attacks. Positives and negatives of other cloud setup were considered. Encryption function is implemented by symmetry-based AES encryption algorithm. This model provides a level of security for each member of that organisation.
