摘要： Systems and methods for trusted integration of untrusted components. An example system includes at least three electrical components and voting (consensus) circuitry. The components have varied hierarchical implementations for providing common output given common input. The voting circuitry is configured to receive, as input, outputs from the components and provide a consensus output that is a majority of the outputs received from the components. Such a diversity of multiple untrusted system components (hardware and/or software) engaged in redundant operation can be integrated to as a consensus-based trusted system with a high degree of fault tolerance to unforeseen environmental interference, cyberattack, supply chain counterfeit, inserted Trojan logic, or component design flaws. The degree of fault tolerance can be increased by increasing the degree of diversity of redundant operational nodes or by increasing the number of diversely implemented operational nodes.

摘要： Each software component loaded for a verified operating system on a client computer must satisfy a set of boot rules for a boot certificate. A verified operating system identifier is created from the boot certificate. The boot certificate is published and signed by a boot authority that attests to the validity of the operating system booted under the boot certificate. Each software component for the operating system is associated with a component certificate published and signed by the same boot authority that signed the boot certificate. The boot rules determine the validity of the software component based on the contents of the component and boot certificates. The client computer transmits the verified operating system identity and the boot certificate to a server computer, such as a content provider, and the content provider determines whether to trust the verified operating system with its content. Downloaded data is secured on permanent storage through a key derived from the verified operating system identifier. The boot certificate, component certificates, and secured content define the boot domain.

摘要： A computing apparatus comprises a plurality of hardware modules (102, 104, 106) and a shared communication infrastructure (110) by which the modules can communicate with each other in the usual way. In order to increase the level of trust and security in the apparatus, a trusted hardware module (120) is also provided and is connected to the other modules by respective communication paths (122a; 122b; 122c), distinct from the communication infrastructure, by which each of those modules can communicate directly with the trusted module but cannot communicate directly with any other of the modules. The trusted module can therefore have secure communications, for example of "unsafe" data, with each of the other modules without any of the remaining modules eavesdropping, and the trusted module can route unsafe data between any pair of the other modules, or decline to provide such routing, for example in dependance on policy stored in the trusted module.

摘要： The present invention is a system and a method for the use of a biometric feature as a key to grant access to a computer. The computer comprises a processor connected to a biometric sensor and a resource for operating the biometric sensor. The processor has a nonenabled state and an enabled state. In the nonenabled state the processor cannot execute applications loaded into memory from a hard drive. In the enabled state the processor can execute such applications. A user gains access to the computer and enables the processor by having a biometric feature input onto the computer using the biometric sensor. The resource that operates the biometric sensor then compares data representing the biometric feature to enrolled user data contained within the resource. If the data representing the biometric feature matches the enrolled user data then the resource switches the processor from the nonenabled state to the enabled state. If there is not a match then the processor remains in the nonenabled state.

摘要： A security enhanced computer system arrangement includes a coprocessor (10) and a multiprocessor logic controller (38) inserted into the architecture of a conventional computer system. The coprocessor and multiprocessor logic controller is interposed between the CPU of the conventional computer system to intercept and replace control signals that are passed over certain of the critical control signal lines associated with the CPU. The CPU is released by allowing control signals to again pass between it and the computer system. Isolating the CPU control signal from the remainder of the computer system, allows a multiprocessor logic controller (38) to interrupt the normal computer system operation at any time and permit the coprocessor to check digital signatures of any firmware or software in the computer system. The multiprocessor logic controller arrangement thereby isolates the CPU of the conventional computer system from the remainder of the conventional computer system, permitting separate control over the CPU and separate control over the remainder of the computer system.

摘要： A method and apparatus for preboot file and information transfer between workstations (13) and other workstations (15) or workstations (13) and servers (11) on local area networks. During a workstation boot sequence, the various components of the workstation and network operating system are loaded and executed. Since all control of the workstation after the boot sequence is passed to the workstation operating system, any mangement tasks performed after boot must be performed by application programs (23) running on the workstation. The present invention overcomes problems created by using such application programs to perform management tasks by providing a hardware component (27), for example a ROM or PROM (61) containing appropriate programming placed in the usually unused boot ROM socket of a LAN card installed in the individual workstations (13), or a chip including a PROM or ROM (61) built onto the motherboard or system board of the individual workstations. The program in the PROM (61) is set up so that, at system start-up (31), prior to loading of the workstation operating system software during the boot sequence, it performs certain operating system functions (35) by using the basic input/output system (BIOS) of the workstation to enable the workstation to communicate with a server on the network and make the necessary resource of the workstation available to a server management application (11c) running on the server via the network. This process, controlled by a system administrator (15), allows a variety of preboot functions to take place in the workstation.
摘要翻译：一种用于在局域网上的工作站（13）和其他工作站（15）或工作站（13）和服务器（11）之间预引导文件和信息传输的方法和装置。在工作站引导顺序期间，加载和执行工作站和网络操作系统的各种组件。由于启动顺序后工作站的所有控制都传递到工作站操作系统，所以在引导之后执行的任何管理任务必须由在工作站上运行的应用程序（23）执行。本发明克服了使用这样的应用程序通过提供硬件组件（27）所产生的问题，该硬件组件（27）例如包含适当编程的ROM或PROM（61），其中所述适当的编程放置在安装在其中的LAN卡的通常未使用的引导ROM插槽中单个工作站（13），或包括建立在各个工作站的主板或系统板上的PROM或ROM（61）的芯片。 PROM（61）中的程序被设置为使得在系统启动（31）期间，在引导顺序期间加载工作站操作系统软件之前，它通过使用基本操作系统执行某些操作系统功能（35）工作站的输入/输出系统（BIOS），以使工作站能够与网络上的服务器进行通信，并使工作站的必要资源可用于经由网络在服务器上运行的服务器管理应用程序（11c）。由系统管理员（15）控制的此过程允许在工作站中进行各种预引导功能。
