SDM based encryption?

For the Stratix 10, I see there is an encryption feature where the SDM decrypts the bitstream. Is there any possibility of using the SDM to support an encrypted FSBL? I’m basically interested in encry...

    Hi LowLevelGuy,

    Apologies for the delay. I was consulting with the internal team to get clarification on this matter.

    When we enabling bitstream encryption on HPS FSBL (included the hex file in the PFG tool), FSBL will be encrypted as well.

    Sorry for the confusion.

    Thank you for your patience.

    Regards,

Hi LowLevelGuy,


From my understanding, yes, enabling bitstream encryption on -AS devices does not automatically encrypt the FSBL. The bitstream encryption specifically targets the FPGA configuration bitstream and does not extend to other software or bootloader code like the FSBL. The Stratix 10's SDM encryption focuses on protecting the FPGA configuration bitstream, not the FSBL or other HPS-related code.
