TPM Trusted PlatformModule
To use the TPM, you must activate the TPM in the BIOS Setup
before the software
is installed
. The condition for this is that you have assigned at least the supervisor
password (see "Security functions", Page 57 ).
Instructions on how to call up and use the
BIOS Setup Utility
can be found in
section "Settings in BIOS Setup Utility", Page 78 .
Enabling TPM
• Requirement: You have set a supervisor password, see "Security functions", Page 57 .
► Call up the BIOS Setup and select the
Security
menu.
► Mark the
TPM (Security Chip) Setting
field and press the Enter key
► Select the
"Security Chip" "Enabled"
entry to activate the TPM
Once you have activated the TPM through a reboot, the
Clear Security Chip
menu option appears.
With
Clear Security Chip
, you can delete the owner in the TPM, if the TPM has already
been used. With
Enabled
, all secret keys generated by applications (e.g. SRK - Storage
Root Keys, AIK - Attestation Identity Keys, etc.) are deleted.
Please note that you will then no longer be able to access the data you have
encrypted with the keys based on that holder.
