    摘要: A migration scheme for virtualized Trusted Platform Modules is presented. The procedure is capable of securely migrating an instance of a virtual Trusted Platform Module from one physical platform to another. A virtual Trusted Platform Module instance's state is downloaded from a source virtual Trusted Platform Module and all its state information is encrypted using a hybrid of public and symmetric key cryptography. The encrypted state is transferred to the target physical platform, decrypted and the state of the virtual Trusted Platform Module instance is rebuilt.

    摘要: The presented method allows a virtual TRUSTED PLATFORM MODULE (TPM) instance to map the Platform Configuration Registers (PCR) register state of a parent virtual TPM instance into its own register space and export the state of those registers to applications inside the virtual machine associated with the virtual TPM instance. Through the mapping of PCR registers, the procedure of attesting to the overall state of a virtual machine can be accelerated, since the state of all measurements relevant to the trustworthiness of a virtual machine are all visible in the combined view of mapped and non-mapped PCR registers. Registers that are mapped into the register space of a virtual TPM instance reflect the state of trustworthiness of those virtual machines that were involved in the creation of the virtual machine that is being challenged.

    摘要: Method, apparatus and computer program product are provided for operating a plurality of computer nodes while maintaining trust. A primary computer node and at least one secondary computer node are connected into a cluster, wherein each of the clustered computer nodes includes a trusted platform module (TPM) that is accessible to software and includes security status information about the respective computer node. Each clustered computer node is then merged into a single node with only the TPM of the primary computer node being accessible to software. The TPM of the primary computer node is updated to include the security status information of each TPM in the cluster. Preferably, the step of merging is controlled by power on self test (POST) basic input output system (BIOS) code associated with a boot processor in the primary node.
