  • Patent number: 8065522
    Abstract: 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.

  • Patent number: 8055912
    Abstract: 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.
