GDoM a multilevel document manager

This paper presents GDoM, a multilevel security document manager. GDoM is an application that offers to diversely cleared users, secure services to store, consult, manage and transfer classified information. It relies on a specific Unix kernel, a multilevel network and a particular machine (M2S: Machine for Multilevel Security) which enforce a complete multilevel security of their data and their processes. This multilevel security makes it possible to enforce a complete security inside an untrusted application like GDoM.
