摘要： Multiple trusted platform modules within a data processing system are used in a redundant manner that provides a reliable mechanism for securely storing secret data at rest that is used to bootstrap a system trusted platform module. A hypervisor requests each trusted platform module to encrypt a copy of the secret data, thereby generating multiple versions of encrypted secret data values, which are then stored within a non-volatile memory within the trusted platform. At some later point in time, the encrypted secret data values are retrieved, decrypted by the trusted platform module that performed the previous encryption, and then compared to each other. If any of the decrypted values do not match a quorum of values from the comparison operation, then a corresponding trusted platform module for a non-matching decrypted value is designated as defective because it has not been able to correctly decrypt a value that it previously encrypted.
摘要翻译：以冗余的方式使用数据处理系统内的多个可信任的平台模块，其提供用于安全地存储用于引导系统可信平台模块的休息处的秘密数据的可靠机制。管理程序请求每个可信平台模块加密秘密数据的副本，从而生成加密的秘密数据值的多个版本，然后存储在可信平台内的非易失性存储器中。在稍后的时间点，加密的秘密数据值由执行先前加密的可信任平台模块进行解密，然后进行比较。如果解密值中的任何一个与比较操作中的值的数量不匹配，则用于非匹配解密值的相应的可信平台模块被指定为有缺陷的，因为它不能正确解密其先前加密的值。

摘要： A method, an apparatus, a system, and a computer program product is presented for virtualizing trusted platform modules within a data processing system. A virtual trusted platform module along with a virtual endorsement key is created within a physical trusted platform module within the data processing system using a platform signing key of the physical trusted platform module, thereby providing a transitive trust relationship between the virtual trusted platform module and the core root of trust for the trusted platform. The virtual trusted platform module can be uniquely associated with a partition in a partitionable runtime environment within the data processing system.

摘要： Embodiments of the present invention address deficiencies of the art in respect to trusted platform module (TPM) unification in a trusted computing environment and provide a novel and non-obvious method, system and computer program product for trusted platform module data harmonization. In one embodiment of the invention, a TPM log harmonization method can include designating both a single master TPM for a master node among multiple nodes, and also a multiplicity of subsidiary TPMs for remaining ones of the nodes. The method further can include extending the single master TPM with a measurement representing a rendezvous operation for the nodes.

摘要： A method, system and computer program product for implementing general purpose PCRs with extended semantics (referred to herein as “ePCRs”) in a trusted, measured software module. The module is designed to run in one of a hypervisor context, an isolated partition, or under other isolated configurations. Because the software module is provided using trusted (measured) code, the software implementing the PCRs is able to run as a simple software process in the operating system (OS), as long as the software is first measured and logged. The software-implemented ePCRs are generated as needed to record specific measurements of the software and hardware elements on which an application depends, and the ePCRs are able to ignore other non-dependencies.
摘要翻译：一种用于在可信测量的软件模块中实现具有扩展语义（在本文中称为“ePCR”）的通用PCR的方法，系统和计算机程序产品。该模块设计为在虚拟机管理程序上下文，隔离分区或其他隔离配置之一下运行。由于使用可信（测量）代码提供软件模块，所以实施PCR的软件只要首先测量和记录软件，就可以在操作系统（OS）中作为简单的软件过程运行。根据需要生成软件实现的ePCR，以记录应用程序所依赖的软件和硬件元素的特定测量，ePCR可以忽略其他不依赖性。

摘要： A system is enabled for configuring an IOMMU to provide direct access to system memory data by at least one I/O device/peripheral. Further, the IOMMU is configured to pass a pointer to at least one I/O device without having to translate the pointer. Further, commands are sent from a process within a guest operating system (OS) directly to a peripheral without intervention from a hypervisor. Further, the IOMMU is configured to grant peripherals access permissions to memory blocks to maintain isolation among peripherals.

摘要： Indicating when the cover for a computer chassis has been opened is disclosed. A computer of an embodiment of the invention includes a chassis and a basic input/output system (BIOS), or another type of firmware. The chassis has an openable cover, and circuitry indicating when the openable cover has been opened. The BIOS has a non-volatile memory in which a flag is set when the circuitry indicates that the openable cover has been opened. The computer may further include always-on circuitry, such as time-of-day and real-time clock circuitry, to which the circuitry indicating when the openable cover has been opened is electrically connected. The computer may also include one or more encryption and/or signing modules that encrypt and/or sign data according to one or more keys. The keys are rendered invalid when the cover of the chassis has been opened.

摘要： The present system enables passing a pointer, associated with accessing data in a memory, to an input/output (I/O) device via an input/output memory management unit (IOMMU). The I/O device accesses the data in the memory via the IOMMU without copying the data into a local I/O device memory. The I/O device can perform an operation on the data in the memory based on the pointer, such that I/O device accesses the memory without expensive copies.

摘要： The present system enables an input/output (I/O) device to request memory for performing a direct memory access (DMA) of system memory. Further, the system uses an input/output memory management unit (IOMMU) to determine whether or not the system memory is available. The IOMMU notifies an operating system associated with the system memory if the system memory is not available, such that the operating system allocates non-system memory for use by the I/O device to perform the DMA.
