Abstract: | Based on trust measurement, a new cross-domain access control model is proposed to improve the security performance of the cross-domain access control processes. This model integrates the trust management and trusted platform measurement, defines several concepts (user trust degree, platform configuration integrity and intra/inter-domain trust degree) and calculates them with users’ uniform identity authentication and historical access behavior analysis. Then this model expands the extensible access control markup language (XACML) model by adding inside trust manager point (ITMP) and outside trust manager point (OTMP), and describes the architectures and workflows of ITMP and OTMP in details. The experimental results show that this model can achieve more fine-grained access control, implement dynamic authorization in a simple way, and improve the security degrees of the cross-domain access control. |
