MLSCPC: Multi-level security using covert channel to achieve privacy through cloud computing

Cloud provider is central processing with shared resources to serve the vendors on demand over the internet where, Cloud model is divided into deployment and service model. In this paper, we address the service model especially privacy where, the privacy allows customers to ensure that their data in cloud not access by unauthorized persons. We implement a novel approach called multi-level security using covert channel to achieve privacy through cloud computing (which we coin it MLSCPC) that enables cloud provider to protect user information from unauthorized persons. We use covert channel to enable cloud provider and customers to communicate in the existence of unauthorized people (e.g. attackers). We have developed a prototype of approach to evaluate its security, feasibility and performance. Our results show that cloud provider can grant customers resources in acceptable time and low computation overhead. Also, attackers don't affect our approach whereby, the cloud provider can grant resources to customers in existent of attackers.
