摘要: This paper describes the capability based protection mechanisms provided by Hydra Operating System Kernel. These support construction of user-defined protected subsystems, including file and directory which do not therefore need to be supplied directly Hydra. In addition, we discuss a number well known problems, Mutual Suspicion, Confinement Revocation, present that supplies in order solve them.
