Abstract

Provided is a method and system for protecting the integrity of a computing system. The system may initialize a plurality of trusted platform modules (TPMs) within the computing system. The system may read a unique identifier corresponding to each TPM of the plurality of TPMs to determine a system state. The system may write the system state to platform configuration registers (PCRs) of each of the plurality of TPMs. The system may load a sealed private owner key part into each TPM of the plurality of TPMs. The plurality of TPMs may determine if a predetermined number of unique identifiers have been processed by validating a value of the PCRs to meet an owner key policy. The plurality of TPMs may unseal the private owner key part in each TPM where the value of the PCRs meets the owner key policy.
