How to use ekp as persistent master key on MAX 10.

I've tried to develop a secure FPGA environment with master key (8.ekp) and encrypted ROM image (*.pof). The idea is to program the master key once before the FPGA left to the customer and the (*.pof...

Hi @JohnT_Intel​ ,

Thanks for your suggestion.

Unfortunately, the only interface that our customer have is JTAG. So using UART communication means a significant redesign is required, thus we don't prefer.

My further question is:

  1. Is the EKP which stored in ICB secure? I see that there's not possible to retrieve the key via JTAG programmer.
  2. Is it also protected from being read? I suppose that the EKP is stored in an unencrypted manner in the ICB.
  3. I see that based on this document https://www.intel.com/content/www/us/en/programmable/documentation/bhc1410500804155.html#bhc1410500737675 in the part of Non-Volatile and Volatile Key Storage, the possibility to program an OTP hardware key (for 20nm FPGAs) is mentioned. Is this the case also for MAX 10 devices? I use 10M04SCM153C8G to be specific.
