TPM (Trusted Platform Module)
Noun | /ˌtiː piː ˈem/
A dedicated microchip or firmware-based security processor that provides hardware-level cryptographic functions. TPMs securely store encryption keys, passwords, and digital certificates to authenticate devices and protect sensitive data.
Key Functions:
- Generates and stores cryptographic keys
- Enables secure boot processes
- Supports disk encryption (e.g., BitLocker)
- Verifies platform integrity
Versions:
- TPM 1.2 (Basic security features)
- TPM 2.0 (Required for Windows 11; supports modern algorithms like SHA-256)
Example:
“Windows 11 requires TPM 2.0 to ensure secure device authentication against firmware attacks.”
