ST33TPHF2XSPI Datasheet STSAFE-TPM ST33TPHF2XSPI: TPM 2.0 device with an SPI interface VFQFPN32 5 × 5 mm Product status link ST33TPHF2XSPI Features TPM features • Flash-memory-based trusted platform module (TPM) • Compliant with Trusted Computing Group (TCG) Trusted Platform Module...
Here we can see the multiple connections to the power supply, BIOS SPI chip, and SVI2 bus (a power management interface) the researchers used on the Lenovo test subject. These connections are used to execute a voltage fault injection attack against the PSP present in Zen 2 and Zen 3 CPUs...
penetration testing systems for their employer and has pointed out and successfully exploited a rather obvious weakness in the BitLocker full volume encryption system, which as the linked article says, allows one to simply sniff the traffic between the discrete TPM chip and CPU via an SPI bus. ...
PICO TPM SNIFFER - SPI libsigrokdecoder_spi-tpm IceStick LPC TPM Snigger SPITKey Trainings Hands-on-security Bitlocker/TPM Hardware training Course The only mitigation for this attack is to enable BitLocker with a PIN OR security key which is adds "Preboot Authentication”. The sniffable key ...
Lastly, fTPMs may share the attack surface with management coprocessors like Intel ME and AMD PSP. On the other hand, fTPMs are much less vulnerable to sniffing by being contained within the CPU package. There are no exposed connections between the TPM and CPU like there is with a dTPM,...

FIFO can operate over serial peripheral interface (SPI) or low pin count (LPC) interface busses. The CRB interface is new for TPM 2.0. It was designed for TPM implementations that use shared memory buffers to communicate commands and responses. Summary This completes the discussion of the TSS...
hardcoded address for data transmission and reception plus some other addresses for handshaking and status operations. The FIFO interface remained mostly the same for TPM 2.0, with a few small changes. FIFO can operate over serial peripheral interface (SPI) or low pin count (LPC) interface bus...
@osresearch@kakaroto@kylerankin@persmule@zaolin: Any update TPMv2 support? @persmule@zaolin: could you point to VBOOT integration docs that would help to port current Heads implementation? @kakaroto: Is Librem key / Nitrokey pro v2 a better way to accomplish this? Will your changes to cor...
memory (RAM)502, and read-only memory (ROM)504via a bus506. The LAN microcontroller/ME further includes multiple I/O interfaces, including network interface508, SPI interface510, PCIe interface512and SMbus interface514. In one embodiment, a cache516is coupled between processor500and SPI ...
