4 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.
Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Security Precautions Security, like any other aspect of computer maintenance requires planning. What is unique about security has to do with understanding who "friends" and adversaries are. The TPM provides mechanisms to enable the owner/user to protect their information from adversaries. To provide this protection the TPM effectively puts "locks" around the data. Just like physical locks, if keys or combinations are lost, the assets (i.e.
Trusted Platform Module Emergency Recovery File Back Up Procedures The Emergency Recovery Token (SPEmRecToken.xml) must be saved or moved to a removable media (floppy, USB drive, CDR, flash media, etc). Once this is done, the removable media should be stored in a secure location. DO NOT LEAVE ANY COPIES of the Emergency Recovery Token on the hard drive or within any hard drive image backups.
Intel Desktop Board D915GEV/D915GUX/D915GAV/D915GAG Product Guide Trusted Platform Module Ownership The Trusted Platform Module is disabled by default when shipped and the owner/end customer of the system assumes “ownership” of the TPM. This permits the owner of the system to control initialization of the TPM and create all the passwords associated with the TPM that is used to protect their keys and data.
Trusted Platform Module 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. done, the removable media should be stored in a secure location. No copies of this Emergency Recovery Token file should remain on the system. If a copy remains on the system, it could be used to compromise the security of the platform. Launch the Infineon Security Platform User Initialization Wizard. Create a Basic User password (this password is the most frequently used and should not match any other password).
