Trusted Platform Modules constitute an integral building block of modern
security features. Moreover, as Windows 11 made a TPM 2.0 mandatory, they are
subject to an ever-increasing academic challenge. While discrete TPMs - as
found in higher-end systems - have been susceptible to attacks on their exposed
communication interface, more common firmware TPMs (fTPMs) are immune to this
attack vector as they do not communicate with the CPU via an exposed bus. In
this paper, we analyze a new class …
