Hardware-Backed Security Using wolfTPM with SPDM

Encrypted Bus Transfers, Multi-Vendor TPM Support, and TCG SPDM Binding Your Secrets Are on the Wire The Problem Discrete TPM chips talk to the host CPU over physical buses: SPI, I2C, or LPC. By default, this communication is unencrypted. Security researchers have repeatedly demonstrated that an attacker with brief physical access can tap these buses […]
