Enable Direct Anonymous Attestation for Dell PowerEdge R250
Hi,
I have a Dell Poweredge R250 server equipped with a Nuvoton TPM version 1.2. I want to execute Direct Anonymous Attestation (DAA) on the server mainly DAA_JOIN and DAA_SIGN commands.
When I try to execute DAA_JOIN command using Trousers-TSS software the response from the TPM is "TPM_DISABLED_COMMAND" which means "The target command has been disabled". I have tried the same software in a Desktop PC with another TPM version 1.2 and it works.
How can I enable DAA for the server?
TPM 1.2
Version Info: Chip Version: 1.2.7.4
Spec Level: 2
Errata Revision: 3
TPM Vendor ID: NTC
Vendor Specific data: 0001
No Events found!

Hello john8019,
I believe there are two possibilities here:
First make sure BIOS is up to date and TPM has been initialized
Initializing the TPM 1.2 for users page 78

Second could be those commands are disabled and not supported in the firmware.
You could contact Support directly for a formal support case and see if it there could be a future feature enhancement.
