Abstract :
The access control mechanism is the one key issue in realizing safety interoperation between distributed information systems. However, the existing multi-domains interoperation access control based on RBAC can not satisfy the safety needs of information system interoperability, in which the sort of users and information are diverse and update frequently. Therefore, the interoperation access control model-DTM-OBAC, based on OBAC and dynamic trust management, was studied in this paper, as to provide a dynamic safety mechanism for information system interoperability across domains.
