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,

  1. Is the EKP which stored in ICB secure? I see that there's not possible to retrieve the key via JTAG programmer.

Yes. You can either write or erase. No read is possible.

  1. Is it also protected from being read? I suppose that the EKP is stored in an unencrypted manner in the ICB.

Yes.

  1. 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.

Max 10 does not support this.
