An efficient, robust, and secure SSO architecture for cloud computing implemented in a service oriented architecture

Implementing Single Sign-On (SSO) in a Cloud space for a spectrum of services and applications is an interesting research avenue for scientific communities in the field of secure identity and access management for Cloud Computing. Using an SSO implementation, in the backend, users can navigate any or all of the supported applications or resources without the need to repeatedly provide credentials. In this chapter, the authors present an efficient and robust Cloud Single Sign-On Architecture (CSSOA) model based on a token security mechanism. Service Oriented Architectures (SOAs) are one of the enabling technologies for solving complex service oriented real world challenges, and hence, CSSOA has been implemented using SOAs. In the authors' CSSOA model, a CSSO SOAP authentication service is distributed among the Cloud servers while the CSSO database service is centralized.
