- W1567109864 abstract "Delegation is a promising alternative to traditional role administration paradigms in role-based systems. It empowers users to exercise discretion in how they use resources as it is in discretionary access control (DAC). Unlike the anarchy of DAC, in role-based access control (RBAC) higher-level organizational policies can be specified on roles to regulate user’s action. Delegations and revocations are thus governed by these authorization policies. In this paper, we propose a policy approach for specifying and enforcing delegation authorizations. We present a mechanism for constructing authorization policies using a set of rules. Our rule-based language is flexible and powerful to specify and enforce authorization constraints. In addition, rules can also be used to define the exceptions for future actions and resolve possible conflicts." @default.
