This paper proposes a method for designing role-based access control (RBAC) using formal concept analysis. By formalizing RBAC triadic matrix as a dyadic security context, we could apply the attribute exploration process in formal concept analysis. The resultant lattice structure represents the role hierarchy and follows separation of duties in RBAC. The proposed method helps to derive the dependencies between the non-mutually exclusive roles, document types, and access permissions.
