Abstract: A service processor is provided that includes a processor, a memory coupled to the processor and having instructions for executing an operating system kernel having an integrity management subsystem, secure boot firmware, and a tamper-resistant secure trusted dedicated microprocessor. The secure boot firmware performs a secure boot operation to boot the operating system kernel of the service processor. The secure boot firmware records first measurements of code executed by the secure boot firmware when performing the boot operation, in one or more registers of the tamper-resistant secure trusted dedicated microprocessor. The operating system kernel enables the integrity management subsystem. The integrity management subsystem records second measurements of software executed by the operating system kernel, in the one or more registers of the tamper-resistant secure trusted dedicated microprocessor.

Abstract: Method, apparatus, and computer program product are provided for merging multiple compute nodes with trusted platform modules utilizing provisioned node certificates. In some embodiments, compute nodes are connected to be available for merger into a single multi-node system. Each compute node includes a trusted platform module (TPM) provisioned with a platform certificate and a signed attestation key (AK) certificate and is accessible to firmware on the compute node. One compute node is assigned the role of master compute node (MCN), with the other compute node(s) each assigned the role of slave compute node (SCN). A quote request is sent from the MCN to each SCN under control of firmware on the MCN. In response to receiving the quote request, a quote response is sent from each respective SCN to the MCN under control of firmware on the respective SCN, wherein the quote response includes the AK certificate of the respective SCN's TPM.

Abstract: A method and computer system for implementing authentication protocol for merging multiple server nodes with trusted platform modules (TPMs) utilizing provisioned node certificates to support concurrent node add and node remove. Each of the multiple server nodes boots an instance of enablement level firmware and extended to a trusted platform module (TPM) on each node as the server nodes are powered up. A hardware secure channel is established between the server nodes for firmware message passing as part of physical configuration of the server nodes to be merged. A shared secret is securely exchanged via the hardware secure channel between the server nodes establishing an initial authentication value shared among all server nodes. All server nodes confirm common security configuration settings and exchange TPM log and platform configuration register (PCR) data to establish common history for future attestation requirements, enabling dynamic changing the server nodes and concurrently adding and removing nodes.

Abstract: A method, apparatus, computer system, and computer program product for releasing secret information. A client on a computer system performing an attestation to a server on another computer system. The client receives an authorization that authorizes releasing the secret information. The client releases the secret information from a co-processor on the computer system using the authorization received from the server.

Abstract: Controlling execution of software is provided. In response to receiving an input to execute a software module on a data processing system, a set of measurements are performed on the software module performing a process to prepare the software module for execution on the data processing system. In response to determining that the set of measurements meets a predetermined criterion, an authorization to proceed with the process of preparing the software module for execution on the data processing system is requested from a trusted third party computer. In response to receiving the authorization to proceed with the process of preparing the software module for execution on the data processing system from the trusted third party computer, the software module is executed.

The method may also include obfuscating the sensitive information and returning, by the secure processing environment, the decrypted data and obfuscated data.

Abstract: Method, apparatus, and computer program product are provided for merging multiple compute nodes with trusted platform modules (TPMs) utilizing an authentication protocol with active TPM provisioning. In some embodiments, compute nodes are connected to be available for merger into a single multi-node system. Each compute node includes a TPM accessible to firmware on the node. One compute node is assigned the role of master compute node (MCN), with the other node(s) each assigned the role of slave compute node (SCN). Active TPM provisioning in each SCN produces key information that is sent to the MCN to enable use of a challenge/response exchange with each SCN. A quote request is sent from the MCN to each SCN. In response to receiving the quote request, a quote response is sent from each respective SCN to the MCN, wherein the quote response includes slave TPM content along with TPM logs and associated signatures.
