Abstract: PURPOSE: A user application memory protecting method is provided to efficiently protect a user application memory without degradation of a virtualized computer system by suing a mechanism which minimizes execution overhead. CONSTITUTION: An executing context is moved from an executing application to a guest OS(Operating System). A hypervisor removes access right to a memory area of the application. The executing context is moved from the guest OS to the application. The hypervisor modifies a page table of a virtual memory area of the application.
Abstract translation: 目的:提供一种用户应用程序存储器保护方法,以有效地保护用户应用程序存储器,而不会因虚拟化计算机系统的恶化而使执行开销最小化的机制。 构成:执行上下文从执行的应用程序移动到客户操作系统(操作系统)。 管理程序删除对应用程序的内存区域的访问权限。 执行上下文从客户操作系统移动到应用程序。 管理程序修改应用程序的虚拟内存区域的页表。
