Classified removable storage medium control based on the access control matrix

According to the research of access control technology, this paper proposed a novel security model to the classified removable storage medium control system. Firstly, we defined a suite of access control strategies among the computer system, users and the classified removable storage medium. And then, we established a security model of the removable storage medium control based on ACM (Access Control Matrix) model combined with access control strategies. Finally, we gave the model´s safety and reliability demonstration on data interaction between the computer system and the classified mobile storage medium.
