Distributed file system over a multilevel secure architecture problems and solutions

Abstract

This paper presents the principles of a distributed and secure file system. It relies on M2S machines and a secure network which control dependencies and avoid any storage and temporal covert channel. It describes how, from NFS (Network File System) principles, we adapt the organization and the structures to obtain practical services despite constraining controls performed by the hardware. Finally it proves that it is possible to obtain a practical distributed file system, with usable features without any compromise on security enforcement.
