Intel Desktop Board D975XBX2 Technical Product Specification 
48   
1.16  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.
