📚 Quick Study Guide: Trusted Platform Module (TPM)
- 🔒 TPM is a secure cryptoprocessor designed to secure hardware by integrating cryptographic keys into devices.
- 🔑 It provides hardware-based security functions, primarily for encryption, authentication, and platform integrity verification.
- 💻 Common uses include secure boot, disk encryption (e.g., BitLocker), password protection, and digital rights management.
- 🛡️ TPMs generate and store cryptographic keys, protecting them from software attacks.
- 🔄 TPM versions: TPM 1.2 (older, fixed functions) and TPM 2.0 (newer, more flexible, supports modern algorithms like ECC). TPM 2.0 is now standard.
- ✅ Secure Boot: TPM works with UEFI/BIOS to ensure that only trusted software loads during startup, preventing rootkits.
- 📜 Attestation: TPM can create cryptographic reports about the system's state, proving its integrity to remote services.
