Abstract
Systems and methods for establishing a shared secret (or pre-shared key (PSK)) between a Chipset and a trusted platform module (TPM) of a computing device that can be used to encrypt all communication between those two components. The PSK may include two (or more) factors that must both be available to the Chipset in order to communicate with the TPM. The first factor may originate from an Endpoint Security Controller (EpSC) and the second factor may originate from within the Chipset. The PSK may only be regenerated by combining multiple segments of a key, referred to as 'factors,' that may be separately assigned to different components of a computing device. If all factors are not provided to a TPM upon boot-up, communication between the Chipset and the TPM may be disabled.
