Abstract:
An information handling system includes a trusted platform module (TPM) and a storage device, the TPM provides boot authentication for the information handling system such that, during a pre-boot phase, the TPM can access a platform configuration register (PCR). During a first instance of the pre-boot phase, the information handling system provides a public/private key pair including a public key and a private key, stores the private key to an encrypted storage of the TPM, seals the private key in the encrypted storage to the PCR, and stores the public key to the storage device. During an operating system phase that is after the first instance of the pre-boot phase, the information handling system retrieves the public key from the storage device, encrypts transfer data using the public key, and stores the encrypted transfer data to the storage device.
