Joint Physical-Layer Attributes-Based Authentication and Authorization Mechanism for Green Cloud Data Centers

Cloud computing can effectively aggregate virtualized computing resources and provide dynamic and economical computing, storage, and various information services for data center terminals. However, with the rapid expansion of cloud data centers, the problems of high energy consumption and carbon emissions have aroused widespread concern. In addition, the traditional authentication mechanism is not suitable for heterogeneous data center networks due to its high resource consumption and low compatibility, which brings security threats to cloud data centers. In this paper, we proposed a lightweight authentication and authorization architecture, which has the advantages of high reliability and security. It does not rely on any communication protocols and has higher compatibility for heterogeneous data center networks. Specifically, the tree-based and support vector-based authentication methods are suggested to enhance identity security. The simulations under real wireless environment verified the effectiveness in authentication performance of the proposed authentication models for green cloud data centers.
