TPM on Embedded Systems: Pitfalls and Caveats to Watch Out For

https://sigma-star.at/assets/images/pingu-neutral.svg
TPM chips provide secure data storage and boot chain integrity, but their use in embedded systems requires careful consideration of physical attacks, session encryption, and attestation protocols. A well-defined threat model and robust hardening measures, such as measured boot and verified boot, are essential to mitigate code execution flaws and ensure the security of TPM keys in embedded systems.

What Is a PC Compatible?

The concept of PC compatibility is a socially defined construct that has evolved over time, making it difficult to technically define what makes a PC compatible. Modern PCs can run old software, but only if it doesn't rely on outdated hardware assumptions, and even then, it may crash or be unusable due to hardware differences.
