Research on User Cross-domain Access Control Model Based on Feedback

Abstract

On the basis of role access control, combined with the role table of this domain and the role table of foreign domains, the inter-domain trust is introduced, and a feedback-based user trust cross-domain access control model-UTKYFKM is proposed. The UTKYFKM model passes trust between different domains. To obtain the user's qualifications to access foreign domains, integrate the user's trust value and resource access execution degree, determine the credibility of user behavior, and combine the foreign domain role table, the system assigns users foreign domain roles, and the user will be externally based on the permissions corresponding to the foreign domain roles. The domain resource object performs the actual access operation and feeds back the execution degree of the access. The feedback feature of this model can detect wrong access control in time and improve the security of cross-domain access control for users.
