1.14 Trusted Platform Module (Optional)
The optional Trusted Platform Module (TPM) is a component on the desktop board that is
specifically designed to enhance platform security above-and-beyond the capabilities of today’s
software by providing a protected space for key operations and other security critical tasks.
Using
both hardware and software, the TPM protects encryption and signature keys at their most
vulnerable stages—operations when the keys are being used unencrypted in plain-text form.
The
TPM is specifically designed to shield unencrypted keys and platform authentication information
from software-based attacks.
