Application information flow non-interference transmission model

In the security field of computer application systems, how to guarantee legal transmission of information flow among different application programs is a significant problem. In this paper, firstly, non-interference theory is analyzed, and then a security model called Application Information Flow Noninterference Transmission Model (AIFNITM) is proposed. The model divides application programs into security domains and sets up rules for regular interference to prevent malicious information flow. Finally, on the basis of AIFNITM, a security enhancement system for an application server is implemented, which demonstrates that the model has strong practicality and operability.
