T1040 documentation states:

The Non-volatile Test Key (NVTK) is a 256-bit key hardwired into SEC. When SEC is in the Non-Secure Mode SEC will use the NVTK to derive Blob key encryption keys, rather than using the secret Master Key. The NVTK value is public knowledge, and is the same in every SOC. It is used for known-answer tests when testing the SEC cryptographic hardware.

 

What is the value so that you can do known answer tests.  I have not been able to determine what it is even though it is suppose to be public knowledge. 

Thanks in advance
