We will explore the journey which lead to the USB armory Mk II R&D to illustrate how state-of-the-art hardware security can be achieved on all kind of embedded systems. We will analyze the interaction of Secure Boot and FDE schemes to understand common patterns in breaking, and fixing, all kind of implementations, whether employed in automotive, consumer or industrial systems. We will delve into the engineering challenges (say Type-C one more time...) that the USB armory Mk II security goals entailed, exploring how this open hardware has been developed.
