TPM Security Enhancements to the Linux Kernel

Learn about critical TPM security enhancements in the Linux kernel through this technical conference talk presented by Microsoft's James Bottomley. Explore how the discrete and firmware-integrated Trusted Platform Module (TPM) verifies boot processes and manages secure secret release, with particular focus on the Systemd Unified Kernel Image implementation. Dive deep into newly upstreamed Linux Kernel TPM security patches that establish secure TPM communication protocols and introduce innovative null key scheme defenses against various TPM-based attacks. Gain comprehensive understanding of TPM attack vectors including interposer attacks, Trusted Computing Group's TPM verification methods, secure communication protocols, and policy statements governing key usage. Discover how the latest Linux Kernel patches enable continuous TPM validation during boot and real-time monitoring for TPM interposer substitutions, enhancing overall system security.
