TPM Protects Private Keys On A Separate Chip
- Trusted Platform Module (TPM) is a separate chip that handles cryptographic functions apart from the CPU and OS.
- The TPM stores a private key on the chip so malware compromising the OS cannot extract it.
Diffie-Hellman Example With Alice
- Rick Howard recounts Diffie and Hellman's invention of the Diffie-Hellman key exchange in 1976.
- He uses the Alice example to show how public and private keys enabled secure messaging without pre-shared secrets.
TPM Standards Evolved Over Decades
- TPM specifications began in 2003 and evolved over time due to early issues with adoption and design.
- ISO published TPM standards and version 2.0 improved the specification to address earlier problems.
