Estendendo o Modelo RBAC de Restrições para Suportar Controle de Acesso Baseado em Quorum de papéis

Altair Oivo SantinEdgard JamhourEmir ToktarEmerson Ribeiro de Mello

This work presents a proposal of extension to the model of Role-Based Access control (RBAC) to support activities that demands mutability in their authorization attributes in runtime. Such activities cannot be subdivided in a set of subtasks executed sequentially and nor they can be accomplished by a single role. The presented approach allows the creation of quorum role, which can only be activated in a session with endorsement of a quorum of other roles.
