WebWe also study PQ Hash-Based signatures (HBS) for image signing and secure boot. In secure boot, there are two or three signature veri cations as the booting process is passed from boot 0 code to a bootloader and then the OS. The signatures that are validated in each step are usually classical RSA signatures which would not be quantum-secure.
