Summary:碩士 === 中原大學 === 資訊工程研究所 === 95 === In this thesis, we explored the role mapping problem between different RBAC systems. Because in an RBAC system, users obtain permissions through the assignment of roles, a user must be assigned a role from other RBAC domains to use the corresponding resources. Therefore one major problem in integrating RBAC domains was to map a role to other domains to obtain desired authorizations in other domains. We proposed a method for role mapping between different RBAC domains. We used permission request concept as basis for role mapping and attempted to produce the least number of temporary roles when acquiring the authorization from different RBAC domains. Our method can assure the consistency of role mapping in a hybrid role hierarchy without changing the role hierarchy in each RBAC domain.
