Abstract
A computer system for failing a secure boot in a case tampering event comprises a microcontroller unit (MCU); a trusted platform module (TPM), for generating random bytes for a secure boot of the computer system; a bootloader, for storing information comprising the random bytes in the MCU and at least one hardware of the computer system and performing the secure boot, wherein the TPM is comprised in the bootloader; an operating system (OS), for performing the secure boot; and at least one sensor, coupled to the MCU, for detecting a case tampering event, and transmitting a signal for triggering a deletion of the random bytes, if the case tampering event happens. The MCU performs the operation of deleting the random bytes stored in the MCU and the at least one hardware according to a power supply, in response to the signal.
