Single Sign-On Algorithm Based on Cloud Computing Concepts for SaaS Applications Using MD5 Encryption
Cloud computing and its services like software as a service infrastructure are becoming important factors in e-commerce and e-business processes. Users may access simultaneously to different services supplied by several providers. An efficient approach to authenticate and authorize users is needed to avoid problems about trust and redundancy of procedure. In this paper, the authors will focus on main approaches in managing Authentication and Authorization Infrastructures (AAI): i.e. federated and centralized and cloud based. Based on the base paper, a cloud-based single sign-on model for reliable accessing to cloud computing software-as-a-service applications.
