    • A computer implemented method for recovering a partition context in the event of a system or hardware device failure. Upon receiving a command from a partition to modify context data in a trusted platform module (TPM) hardware device, a trusted platform module input/output host partition (TMPIOP) provides an encrypted copy of the context data and the command to the TPM hardware device, which processes the command and updates the context data. If the TPM hardware device successfully processes the command, the TMPIOP receives the updated context data from the TPM hardware device and stores the updated context data received in encrypted form in a context data cache or a non-volatile storage off-board the TPM hardware device. If the TPM hardware device fails to successfully process the command, the TMPIOP uses a last valid copy of the context data to retry processing of the command on a different TPM hardware device.
    • 一种用于在系统或硬件设备故障的情况下恢复分区上下文的计算机实现的方法。 信任平台模块输入/输出主机分区(TMPIOP)在接收到来自分区的命令以修改可信平台模块(TPM)硬件设备中的上下文数据时,将上下文数据的加密副本提供给TPM硬件设备 ,它处理命令并更新上下文数据。 如果TPM硬件设备成功地处理该命令,则TMPIOP从TPM硬件设备接收更新的上下文数据,并将以加密形式接收到的更新的上下文数据存储在上行数据高速缓存或TPM硬件设备的非易失性存储器 。 如果TPM硬件设备无法成功处理该命令,则TMPIOP将使用上一个上下文数据的最后一个有效副本来重试不同TPM硬件设备上的命令处理。

    • A method, apparatus, and computer program product are described for implementing a trusted computing environment within a data processing system where the data processing system includes a single hardware trusted platform module (TPM). Multiple logical partitions are provided in the data processing system. A unique context is generated for each one of the logical partitions. When one of the logical partitions requires access to the hardware TPM, that partition's context is required to be stored in the hardware TPM. The hardware TPM includes a finite number of storage locations, called context slots, for storing contexts. Each context slot can store one partition's context. Each one of the partitions is associated with one of the limited number of context storage slots in the hardware TPM. At least one of the context slots is simultaneously associated with more than one of the logical partitions. Contexts are swapped into and out of the hardware TPM during runtime of the data processing system so that when ones of the partitions require access to the hardware TPM, their required contexts are currently stored in the hardware TPM.
    • 描述了一种在数据处理系统内实现可信计算环境的方法,装置和计算机程序产品,其中数据处理系统包括单个硬件可信平台模块(TPM)。 在数据处理系统中提供了多个逻辑分区。 为每个逻辑分区生成唯一的上下文。 当其中一个逻辑分区需要访问硬件TPM时,该分区的上下文需要存储在硬件TPM中。 硬件TPM包括有限数量的存储位置,称为上下文时隙,用于存储上下文。 每个上下文时隙都可以存储一个分区的上下文。 每个分区与硬件TPM中的有限数量的上下文存储时隙中的一个相关联。 至少一个上下文时隙同时与多于一个的逻辑分区相关联。 在数据处理系统的运行期间,上下文交换进出硬件TPM,以便当这些分区中的一个需要访问硬件TPM时,其所需的上下文当前存储在硬件TPM中。

    • Methods, systems, and media for remote control of a vehicle device and vehicle lockout notification are disclosed. Embodiments comprise a method of creating a secure bidirectional communication link between a remote access device and a central locking unit (CLU) of a vehicle, enabling the central locking unit to authenticate a user of the remote access device to manipulate a device of the vehicle. In some embodiments, the CLU may wait for an access attempt from a mobile device. In other embodiments, the CLU monitor vehicle conditions, detect a lockout condition, and alert the user before authenticating and granting vehicle access. Embodiments utilize private and shared key encryption methods to facilitate securely passing an access code between the CLU and the remote access device. Some embodiments authenticate the user by voice verification, while other embodiments may use personal identification numbers.

    • A method is presented for implementing a trusted computing environment within a data processing system. A hypervisor is initialized within the data processing system, and the hypervisor supervises a plurality of logical, partitionable, runtime environments within the data processing system. The hypervisor reserves a logical partition for a hypervisor-based trusted platform module (TPM) and presents the hypervisor-based trusted platform module to other logical partitions as a virtual device via a device interface. Each time that the hypervisor creates a logical partition within the data processing system, the hypervisor also instantiates a logical TPM within the reserved partition such that the logical TPM is anchored to the hypervisor-based TPM. The hypervisor manages multiple logical TPM's within the reserved partition such that each logical TPM is uniquely associated with a logical partition.
    • 呈现一种用于在数据处理系统内实现可信计算环境的方法。 在数据处理系统内初始化管理程序,并且管理程序监视数据处理系统内的多个逻辑,可分割的运行时环境。 虚拟机管理程序为基于虚拟机管理程序的可信平台模块(TPM)预留逻辑分区,并通过设备接口将基于虚拟机管理程序的可信平台模块作为虚拟设备呈现给其他逻辑分区。 每当虚拟机管理程序在数据处理系统内创建一个逻辑分区时,管理程序也会在保留的分区内实例化一个逻辑TPM,使得逻辑TPM被锚定到基于管理程序的TPM。 虚拟机管理程序管理保留分区内的多个逻辑TPM,使得每个逻辑TPM与逻辑分区唯一相关联。
