摘要： 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.

摘要： A trusted platform module is presented that is capable of creating, dynamically, multiple virtual trusted platform modules in a hierarchical organization. A trusted platform module domain is created. The trusted platform module creates virtual trusted platform modules, as needed, in the trusted platform module domain. The virtual trusted platform modules can inherit the permissions of a parent trusted platform module to have the ability to create virtual trusted platform modules themselves. Each virtual trusted platform module is associated with a specific partition. Each partition is associated with an individual operating system. The hierarchy of created operating systems and their privilege of spawning new operating systems is reflected in the hierarchy of trusted platform modules and the privileges each of the trusted platform modules has.

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： 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： A method and apparatus 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 key, which is stored only within a corresponding virtual TPM. Using the virtual endorsement key, each virtual TPM also 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.

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.
