Securing Your Computer 85
Trusted Platform Module (TPM)
NOTE: The TPM feature supports encryption only if the operating system supports
TPM. For more information, see the TPM software documentation and the help files
that came with the software.
TPM is a hardware-based security feature that can be used to create and
manage computer-generated encryption keys. When combined with security
software, the TPM enhances existing network and computer security by
enabling features such as file protection capabilities and protected e-mail.
The TPM feature is enabled through a system setup option.
NOTICE: To secure your TPM data and encryption keys, follow the backup
procedures documented in the Broadcom Secure Foundation Getting Started
Guide
. In the event of these backups being incomplete, lost, or damaged, Dell will
be unable to assist in the recovery of encrypted data.
