摘要内容:

For the complexity of the multi-domain environment and the multi-domain environment of the information secure sharing, the traditional access control method can not ensure the absolute security for the exchange of data resources. Through introducing the concept of risk, this paper proposes a dynamic access control model for multi-domain environment based on risk of inter-operations. The risk rank of an access policy can be calculated by the history of the inter-operations among domains, the security degree of the objects and the safety factor of the access events.Through adjusting the access policies which be considered the high risk, the risk in the system can be controlled in real time. The security analysis shows that this method can reinforce the facility of the access control and the security of the multi-domain environment.
