摘要： In an array of groups of cryptographic processors, the processors in each group operate together but are securely connected through an external shared memory. The processors in each group include cryptographic engines capable of operating in a pipelined fashion. Instructions in the form of request blocks are supplied to the array in a balanced fashion to assure that the processors are occupied processing instructions.

摘要： In a communications channel coupled to multiple duplicated subsystems, a method, interposer and program product are provided for verifying integrity of subsystem responses. Within the communications channel, a first checksum is calculated with receipt of a first response from a first subsystem responsive to a common request, and a second checksum is calculated for a second response of a second subsystem received responsive to the common request. The first checksum and the second checksum are compared, and if matching, only one of the first response and the second response is forwarded from the communications channel as the response to the common request, with the other of the first response and the second response being discarded by the communications channel.

摘要： Provides a software-to-software interface and a software-to-hardware interface between software users and a hardware ADM facility (ADMF) in a data processing system. Such software user presents only virtual addresses to the software-to-software interface in a MSB list. The user list defines virtual address spaces, including a "hiperspace", in a manner that represents physical backing media as different random-access electronic storages, such main storage (MS) and expanded storage (ES). The real data transfers are within or between the backing storages. The user list is transformed into an ADM operation block (AOB), which is assigned an ADM UCB in a UCB queue which is associated with an ADM subchannel. The software-to-hardware interface generates an ORB, containing the AOB address, as an operand of a SSCB instruction which is executed to queue the associated subchannel onto one of plural co-processor queues in the ADMF. The ADMF uses the AOB to perform the requested page moves, and generates an interruption upon completion of each request which is sent to the hardware-to-software interface to remove the associated ADMF request from the ADM software request queue and free the associated ADM UCB for use by another user request.

摘要： 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.
摘要翻译：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。

摘要： A multiprocessor system which includes automatic workload distribution. As threads execute in the multiprocessor system, an operating system or hypervisor continuously learns the execution characteristics of the threads and saves the information in thread-specific control blocks. The execution characteristics are used to generate thread performance data. As the thread executes, the operating system continuously uses the performance data to steer the thread to a core that will execute the workload most efficiently.

摘要： A system for implementing computer security is provided. The system includes a computer processor and an application configured to execute on the computer processor, the application implementing a method that includes creating a token and populating a payload section of the token with key material and selecting a wrapping method that specifies how the key material is securely bound to key control information. A structure of the key control information in the token is independent of the wrapping method. Implementing computer security also includes wrapping the key material and binding key control information to the key material in the token. The key control information includes information relating to usage and management of the key material.

摘要： Multiple logical partitions are provided in a 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.
