AbstractA TPM-based industrial control trusted embedded platform activation method, the method comprising: after an embedded platform is powered up, a root of trust (CRTM) acting as an anchor for, and executing, a chain of trust; performing BIOS trust measurement, and activating the BIOS after measurement is passed; the BIOS measuring a Bootloader, expanding a measurement value into a PCR corresponding to a TPM, and after measurement is passed, handing over a control execution right to the Bootloader; the Bootloader measuring an OS kernel activation process, recording a measurement value thereof in the PCR of the TPM, and after measurement is passed, executing an activation process of an OS. The present method obtains a measurement before activation at every part of an activation process, and measurement values are stored in a PCR corresponding to a TPM; when an activation process is tampered with by an attacker, a completion measurement mechanism terminates execution of the process, thereby ensuring security of an embedded platform.
