Figure 5-1. Bootloader integrity and authencity

The MAC protects against modification of the bootloader and depends on the (secret)
boot key.

Only if the calculated MAC value matches the stored boot MAC value: a successful
secure boot occurs, and keys become unlocked for further use.

5.3.2 Chain of trust: check flash memory for integrity and

authenticity

In this use case:

• The bootloader is protected by the secure boot process.
• MACs stored in the bootloader provide integrity and authenticity of the related parts

in flash memory.

• Part-by-part checking of flash memory ensures each part's integrity and authenticity

before executing it. Critical parts of flash memory (for example, MCU
configuration/IRQ table) are checked and then executed as soon as possible.
