摘要

The term cloud (in the context of computing systems) refers to systems and applications that integrate and manage sharing of resources and services distributed across multiple administrative domains. Performance with scalability, optimum utilization of resources, efficient management and reliability and virtualization are some of the advantages of cloud applications. Most of the existing research on cloud security is focussed on authentication. Access control and authorization is a relatively less explored area, although very important for cloud security. The potential of access control as a security mechanism in grids is one of the major motivating factors behind this work. Design and development of new models for access control and authorization, specific to cloud environment and its security requirements forms the core of this thesis work. The thesis proposes models for representing various access control components of cloud security and suggests algorithms to show the association between these components. Our study on the access control and authorization requirements of cloud systems helped us to identify the core cloud security issues as cloud-wide access control and authorization, indirect authorization for the geographically spread users and resources, dynamic authorization of the cloud resources. Since a cloud-wide mechanism to secure the cloud resources does not exist, we proposed an multi-level authendiction framework. This framework includes one time password, team level and user level password generation authorization architectures. Multi dimensional password generation algorithms govern the working of this architecture. We implemented the cloud authorization model for team level and user level enforcement of access control. We implemented the models using programming techniques and inference mechanisms.
