A historical case study analyzing high-profile security research that bypassed BitLocker, Chromebook, and server hardware roots of trust via unencrypted bus sniffing.
We examine landmark security demonstrations where researchers utilized low-cost Raspberry Pi Pico devices and oscilloscope probes to capture BitLocker VMK (Volume Master Keys) from SPI buses on commercial laptops in under 45 seconds, exposing the critical flaw of trusting external PCB buses.
How the Trusted Computing Group responded by developing session-based parameter encryption protocols, and why classical Diffie-Hellman session key exchange must now be upgraded to post-quantum ML-KEM to protect long-term encrypted assets.
PCB routing best practices, buries traces on internal inner layers, ground plane shielding, microvia placement, and the mandatory enablement of hardware bus encryption in next-generation motherboard chipsets.
