    • Techniques for enabling client computing devices to leverage remote server pools for increasing the effectiveness of applications stored on the client computing device are described herein. In some instances, the server pools comprise a “cloud”, “cluster” or “data center” that comprises hundreds or thousands of servers connected together by a network that has an extremely low latency and high bandwidth relative to the network through which the client computing device connects to the server pool. The client computing device may request that the server pool perform a certain task for an application whose canonical state resides on the client. After computation of a result of the task, a server of the server pool then provides the result to the client. By doing so, the techniques dramatically increase the amount of resources working on the request of the client and, hence, dramatically increase the speed and effectiveness of the client-side application.
    • 本文描述了使客户端计算设备能够利用远程服务器池来增加存储在客户端计算设备上的应用的有效性的技术。 在某些情况下,服务器池包括一个“云”,“集群”或“数据中心”,其中包含数百或数千个由网络连接在一起的服务器,网络具有相对于网络极低的延迟和高带宽,客户端 计算设备连接到服务器池。 客户端计算设备可以请求服务器池为其规范状态驻留在客户端上的应用执行特定任务。 在计算任务的结果之后,服务器池的服务器然后将结果提供给客户端。 通过这样做,这些技术大大增加了根据客户端请求工作的资源量,从而大大提高了客户端应用程序的速度和有效性。

    • Techniques for leveraging legacy code to deploy native-code desktop applications over a network (e.g., the Web) are described herein. These techniques include executing an application written in native code within a memory region that hardware of a computing device enforces. For instance, page-protection hardware (e.g., a memory management unit) or segmentation hardware may protect this region of memory in which the application executes. The techniques may also provide a narrow system call interface out of this memory region by dynamically enforcing system calls made by the application. Furthermore, these techniques may enable a browser of the computing device to function as an operating system for the native-code application. These techniques thus allow for execution of native-code applications on a browser of a computing device and, hence, over the Web in a resource-efficient manner and without sacrificing security of the computing device.
    • 本文描述了利用传统代码通过网络(例如,Web)来部署本地代码桌面应用程序的技术。 这些技术包括执行在计算设备的硬件实施的存储器区域内以本地代码编写的应用程序。 例如,页面保护硬件(例如,存储器管理单元)或分段硬件可以保护应用程序执行的存储器区域。 这些技术还可以通过动态地执行由应用程序进行的系统调用来提供超出该存储器区域的窄系统调用接口。 此外,这些技术可以使得计算设备的浏览器能够用作本地代码应用的操作系统。 因此,这些技术允许在计算设备的浏览器上执行本地代码应用,并因此允许以资源有效的方式在Web上执行,而不会牺牲计算设备的安全性。

    • Techniques for utilizing trusted hardware components for mitigating the effects of equivocation amongst participant computing devices of a distributed system are described herein. For instance, a distributed system employing a byzantine-fault-resilient protocol—that is, a protocol intended to mitigate (e.g., tolerate, detect, isolate, etc.) the effects of byzantine faults—may employ the techniques. To do so, the techniques may utilize a trusted hardware component comprising a non-decreasing counter and a key. This hardware component may be “trusted” in that the respective participant computing device cannot modify or observe the contents of the component in any manner other than according to the prescribed procedures, as described herein. Furthermore, the trusted hardware component may couple to the participant computing device in any suitable manner, such as via a universal serial bus (USB) connection or the like.
    • 在此描述了利用可信硬件组件来减轻分布式系统的参与者计算设备之间的混淆效应的技术。 例如,采用拜占庭故障弹性协议的分布式系统 - 即旨在减轻(例如,容忍,检测,隔离等)拜占庭故障的影响的协议 - 可以采用这些技术。 为了这样做,这些技术可以利用包括非递减计数器和密钥的可信硬件组件。 该硬件组件可能是“可信赖的”,因为如本文所述,相应的参与者计算设备不能以除了根据规定的过程之外的任何方式修改或观察组件的内容。 此外,可信硬件组件可以以任何合适的方式,例如经由通用串行总线(USB)连接等耦合到参与者计算设备。
