Abstract

The secure OS has been the focus of several studies. However, CPU resources, which are important resources for executing a program, are not the object of access control in secure OS. For preventing the abuse of CPU resources, we had earlier proposed a new type of execution resource that controls the maximum CPU usage (Tabata et al. in Int. J. Smart Home 1(2):109---128, 2007). The previously proposed mechanism can control only one process at a time. Because most services involve multiple processes, the mechanism should control all the processes in each service. In this paper, we propose an improved mechanism that helps to achieve a bound on the execution performance of a process group in order to limit unnecessary processor usage. We report the results of an evaluation of our proposed mechanism.
