Abstract: Methods, systems, and computer program products are provided for machine-specific instruction set translation. One example method includes identifying computing devices, each device having a respective software component installed, the software component including a translator component for translating a program in a portable format to a machine-specific instruction set, and a sandbox component for executing programs translated to the machine-specific instruction set on the computing device using software-based fault isolation; identifying computing devices having a given hardware configuration; and transmitting another translator component and another sandbox component to each of the identified computing devices. Each of the identified computing devices having the given hardware configuration is configured to receive the components and to configure its software component to use the received components in lieu of the corresponding components.

Abstract: A system that safely executes a native code module on a computing device. During operation, the system receives the native code module, which is comprised of untrusted native program code expressed using native instructions in the instruction set architecture associated with the computing device. The system then loads the native code module into a secure runtime environment, and proceeds to execute a set of instructions from the native code module in the secure runtime environment. The secure runtime environment enforces code integrity, control flow integrity, and data integrity for the native code module. Furthermore, the secure runtime environment moderates which resources can be accessed by the native code module on the computing device and/or how these resources can be accessed. By executing the native code module in the secure runtime environment, the system facilitates achieving native code performance for untrusted program code without a significant risk of unwanted side effects.
Abstract translation: 一种在计算设备上安全执行本机代码模块的系统。 在操作期间，系统接收本地代码模块，其由使用与计算设备相关联的指令集架构中的本地指令表示的不可信的本机程序代码组成。 然后，系统将本机代码模块加载到安全运行时环境中，并继续在安全运行时环境中从本机代码模块执行一组指令。 安全运行时环境强制本机代码模块的代码完整性，控制流完整性和数据完整性。 此外，安全运行时环境调节哪些资源可以由计算设备上的本地代码模块访问和/或如何访问这些资源。 通过在安全运行时环境中执行本地代码模块，系统便于实现不可信程序代码的本地代码性能，而不会产生不必要的副作用的重大风险。

Abstract: Some embodiments provide a system that executes a native code module. During operation, the system obtains the native code module. Next, the system loads the native code module into a secure runtime environment. Finally, the system safely executes the native code module in the secure runtime environment by using a set of software fault isolation (SFI) mechanisms that constrain store instructions in the native code module. The SFI mechanisms also maintain control flow integrity for the native code module by dividing a code region associated with the native code module into equally sized code blocks and data blocks and starting each of the data blocks with an illegal instruction.
Abstract translation: 一些实施例提供执行本地代码模块的系统。 在操作过程中，系统获取本地代码模块。 接下来，系统将本机代码模块加载到安全运行时环境中。 最后，系统通过使用一组限制本地代码模块中的存储指令的软件故障隔离（SFI）机制来安全地执行安全运行时环境中的本机代码模块。 SFI机制还通过将与本地代码模块相关联的代码区域划分为相等大小的代码块和数据块以及以非法指令启动每个数据块，来保持本地代码模块的控制流完整性。

Abstract: A system that validates a native code module. During operation, the system receives a native code module comprised of untrusted native program code. The system validates the native code module by: (1) determining that code in the native code module does not include any restricted instructions and/or does not access restricted features of a computing device; and (2) determining that the instructions in the native code module are aligned along byte boundaries such that a specified set of byte boundaries always contain a valid instruction and control flow instructions have valid targets. The system allows successfully-validated native code modules to execute, and rejects native code modules that fail validation. By validating the native code module, the system facilitates safely executing the native code module in the secure runtime environment on the computing device, thereby achieving native code performance for untrusted program binaries without significant risk of unwanted side effects.
Abstract translation: 验证本机代码模块的系统。 在操作期间，系统接收由不可信的本地程序代码组成的本地代码模块。 该系统通过以下方式来验证本地代码模块：（1）确定本地代码模块中的代码不包括任何受限制的指令和/或不访问计算设备的受限特征; 和（2）确定本地代码模块中的指令沿着字节边界排列，使得指定的字节边界集合总是包含有效指令，并且控制流指令具有有效目标。 系统允许成功验证的本地代码模块执行，并拒绝验证失败的本机代码模块。 通过验证本地代码模块，系统便于在计算设备上的安全运行时环境中安全执行本地代码模块，从而为不受信任的程序二进制代码执行本机代码性能，而不会产生不必要的副作用。
