Using the TPM
The Trusted Platform Module (TPM) may be embedded in your computer to provide basic security functions. In combination
with the TPM, you can encrypt and decrypt your data to strengthen computer security against inappropriate access.
See the specifications to find out about the configuration of your computer.
TPMs are defined by Trusted Computing Group (TCG) and also called security chips.
Important Notice
❑
Do not encrypt the files containing keys to be used for encryption and the folders that include such files.
Encrypting the files in the folders containing basic user keys and others, using the Encrypting File System (EFS) will
disable you to launch your TPM software and decrypt the encrypted data in the following cases:
❑
The TPM software has been installed.
❑
The platform has been initialized.
❑
The EFS function has been enabled in user initialization process.
With the default settings, the files in the folders below cannot be encrypted because they have system attributes.
Do not change the system attributes of the files in the folders below.
!
The following folders are invisible by default.
❑
Folders containing basic user keys and others
C:\<username>\All Users\Infineon\TPM Software 2.0\BackupData
C:\<username>\All Users\Infineon\TPM Software 2.0\PlatformKeyData
C:\<username>\All Users\Infineon\TPM Software 2.0\RestoreData
