- Abstract
- It is barely conceivable to ensure the security state of a device without a trusted computing base. However, a hardware security module is not provided in most low-power devices. This paper presents a new design approach, which can securely verify a current state of firmware at a booting time utilizing untrusted components. We discuss a Memory Protection Unit (MPU) enabled memory access control to ensure that memory regions of a bootloader are not accidentally compromised from unintended access. Further extensions of the suggested approach are also addressed for achieving the enhanced security confirmation.
