Abstract

This paper proposes a knowledge-based approach to Internet authorizations using Public-Key Infrastructure (PKI) based digital certificates and Role-Based Access Control (RBAC). First, we introduce several existing access control models. Second, a logic-based policy specification language is given. Third, a policy-driven RBAC is presented. Fourth, a method of automatically assigning roles to users using digital certificates is discussed. Then, the architecture for Internet authorizations is described. Finally, a solution to remote policy enforcement is proposed. We also give the syntax of a role definition language and illustrate it in appendices A and B, respectively.
