Abstract: 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.

Abstract: A method for puncture of the inter-atrial septum of a heart is performed by means of a laser catheter assembly comprising at least one longitudinal sheath and an optical fiber connectable to a laser energy source. The components of the laser catheter assembly are perveneously introduced and advanced into the right atrium until the sheath is in intimate contact with the septal wall and laser light is applied via said optical fiber and emitted on the tissue located in front of the distal end of the fiber so as to create a small hole in said inter-atrial septum.

Ventricular outflow tract obstructions may be substantially reduced or even abolished when laser light is applied to the hypertrophied tissue so as to produce a coagulation necrosis inside the hypertrophied septal wall.

Abstract: A method, apparatus, and computer program product are disclosed in a data processing system for establishing virtual endorsement credentials. The data processing system includes a hardware trusted platform module (TPM). Logical partitions are generated in the system. A different virtual TPM is generated for each one of the logical partitions. For each one of the logical partitions, the virtual TPM that was generated for the logical partition then dynamically generates a virtual endorsement credential for use by the logical partition that includes the virtual TPM. The virtual endorsement credential is generated within the data processing system without the data processing system or its devices accessing a trusted third party that is external to the data processing system.

Abstract: 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.

Abstract: A method, apparatus, and computer program product are described for implementing a trusted computing environment within a data processing system. The data processing system includes a primary hardware trusted platform module (TPM) and a secondary hardware backup TPM. The data processing system also includes multiple logical partitions. The primary hardware TPM is used to provide trusted computing services to the logical partitions. A determination is made as to whether the primary hardware TPM is malfunctioning. If a determination is made that the primary hardware TPM is malfunctioning, the secondary hardware TPM is designated as a new primary hardware TPM and is utilized instead of the primary TPM to provide trusted computing services to the logical partitions.

Abstract: A method, system and computer program product for enhancing the functionality of the existing core root of trust measurement (CRTM). The CRTM is extended to allow platform manufacturer controlled and certified code to be incorporated into the function of the CRTM, wherein the manufacturer may define the policy for accepting a new function into the CRTM. When a firmware or software module image is compiled, the build process generates a hash value of the compiled firmware or software image, wherein the hash value reflects a fingerprint (or short hand) representation of the compiled image. A determination is made as to whether the hash value of the firmware or software image is to be a CRTM extension. If so, a digital signature of the module is created using the CRTM extension private key. This signature value is added to the firmware or software module.
