In order to solve the existed problems of dynamic integrity measurement method, a dynamic integrity measurement model based on Memory Paging Mechanism is proposed in this paper. The model takes memory pages of executable subjects as measurement objects. When the pages are scheduled into memory, the measurement points are inserted, the pages are measured, and their integrities are verified. The model is able to insure the integrity and trust of each executable page and assure that the integrity of the whole executable subjects is not destroyed. To verify this model, XEN hypercall mechanism is used to acquire executable subjects’ pages scheduled into memory, and the integrity measurement and verification codes are put into hypercall handler. Accordingly, dynamic integrity measurement to executable subjects is implemented
