Single sign-on in cloud computing scenarios: A research proposal

Abstract

Cloud computing and Software as a Service infrastructure are becoming important factors in E-commerce and E-business processes. Users may access simultaneously to different E-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 we will focus on main approaches in managing Authentication and Authorization Infrastructures (AAI): i.e. federated and centralized and cloud based. Then we will discuss about related some critical issues in Cloud computing and SaaS contexts and will highlight the possible future researches. © Springer-Verlag 2011.
