Especificação baseada no padrão UPnP para autenticação e autorização de usuários em ambientes de computação pervasiva.

Abstract

The paradigm of Pervasive Computing is slowly becoming a reality motivated by different aspects such as cheaper mobile devices, the wide dissemination of wireless network technologies and the techniques of software development for devices with restricted resources. In addition, this paradigm embraces a world where computing services are seamlessly integrated to the people’s everyday lives. The UPnP standard is a good candidate for device discovery and pervasive service provisioning. However, the standard does not address user authentication and authorization mechanisms, important features for defining and building customized services and access control to network resources. Therefore, UPnP service developers must cope with third party user authentication and authorization solutions, which turns interoperability a difficult process to be accomplished. This work proposes a UPnP-based user authentication and authorization specification for pervasive computing environments. Such specification provides a connectivity architecture for user profile availability service, also allowing the definition of access control policies for secure UPnP services. Within this context, this work presents two case studies: one for multimedia content recommendation and another for access control to network devices.
