RESUMO

Distributed computing has been expanding its scope from local area network applications to wide-area applications, involving different organizations. This expansion implies in several new security challenges, such as the identification of users originating from different organizations and the definition of their access rights. Commom aproaches involve replicating user data in several institutions or sharing identities among sets of users. However, these approaches have several limitations, sucj as the increased management effort of administrators or problems with privacy policies. This work proposes a framework for inter-institucional authentication. The framework is based on the concepts of RBAC (role-based access control) and of trust between organizations.
