Compatible Trusted Platform Module (TPM) Security Device cannot be found…


TPM error – A compatible Trusted Platform Module (TPM) Security Device cannot be found on this computer. TBS could not be started.

Interesting warning right?

The short answer is that you either have a TPM that is older (not Version 1.2 or greater), or your TPM is not enabled in the BIOS or has some other problem that is preventing it’s required services (TBS) from starting.  The implication is thus: You will not be able to take advantage of additional security measures offered to systems that have a compatible TPM.  This is significant for users of Microsoft’s BitLocker technology.
On computers that do not have a TPM version 1.2, you can still use BitLocker to encrypt the Windows operating system drive.  However, this implementation will require the user to insert a USB startup key to start the computer or resume from hibernation, and it does not provide the pre-startup system integrity verification offered by BitLocker with a TPM.

TPM – The TPM is a microcontroller that stores keys, passwords and digital certificates. It typically is affixed to the motherboard of a PC.  The nature of this silicon ensures that the information stored there is made more secure from external software attack and physical theft.  Access to data and secrets in a platform could be denied if the boot sequence is not as expected.

TBS – TPM Base Services – The interface between the TPM and the programs that use it, including Microsoft BitLocker (used to encrypt and otherwise lockdown hard drives on your computer to protect in the case of theft or other unauthorized access)
