    Abstract: This document describes tools capable of making a portion of operating-system memory associated with a protection agent unalterable or inaccessible from an operating-system privilege mode. In some embodiments, these tools are capable of creating a protection-agent privilege mode by requesting that a virtual machine monitor protect this portion of operating-system memory. In other embodiments, these tools are capable of creating the protection-agent privilege mode by virtualizing a physical processor into multiple virtual processors, at least one of which is a protection-agent virtual processor designed to run the protection agent. By making this portion of operating-system memory unalterable or inaccessible from the operating-system privilege mode, the protection agent may be less vulnerable to attacks by entities operating within the operating-system privilege mode.

    Abstract translation: 本文档描述了能够使与操作系统特权模式不可更改或不可访问的保护代理相关联的操作系统内存的一部分的工具。 在一些实施例中,这些工具能够通过请求虚拟机监视器保护操作系统存储器的这一部分来创建保护代理特权模式。 在其他实施例中,这些工具能够通过将物理处理器虚拟化为多个虚拟处理器来创建保护代理特权模式,其中至少一个虚拟处理器是被设计为运行保护代理的保护代理虚拟处理器。 通过使操作系统内存的这一部分从操作系统特权模式变得不可改变或不可访问,保护代理可能不太容易受到在操作系统特权模式下操作的实体的攻击。

    Abstract: A computer includes a housing (100), a processor (120) positioned in the housing (100), and an external bus adapter (105, 110) configured to allow the processor (120) to access consumer electronics devices positioned outside of the housing (100) using an external bus. The processor (120) is configured to produce a first digital audio signal, to mix the first digital audio signal with a second digital audio signal to produce a unified digital audio signal, and to transmit the unified digital audio signal to a consumer electronics device using the external bus.

    Abstract: This document describes tools capable of enabling a protection agent to determine, from memory inaccessible from an operating-system privilege mode, whether one or more resources of an operating system have been modified. In some instances, these tools may enable the protection agent to reside within a virtual machine monitor. In other instances, the tools may enable the protection agent to reside within a distinct virtual partition provided by the virtual machine monitor. By operating outside of the operating-system privilege mode, the protection agent may be less vulnerable to attacks by entities operating within the operating-system privilege mode.

    Abstract translation: 本文档描述了能够使保护代理能够从不能从操作系统特权模式访问的存储器确定操作系统的一个或多个资源是否已被修改的工具。 在某些情况下,这些工具可能使保护代理能够驻留在虚拟机监视器中。 在其他情况下,这些工具可以使保护代理能够驻留在由虚拟机监视器提供的不同的虚拟分区中。 通过在操作系统特权模式之外操作,保护代理可能不太容易受到在操作系统特权模式下操作的实体的攻击。
