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.

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.

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.
