Arria 10 flash security

Hello, We're using Arria 10 with EPCQ device, and looking for solutions to protect the EPCQ content. The EPCQ is used for holding both the configuration bitstream and also other data. Configur...

    Regarding to question 2, no we cant access to the AES modules.

Are you saying that you want to write the encrypted bitstream using NIOS into flash? If it so, need to use the existing mechanism.

    No, I'm not talking about the bitstream.
    I'll try to be more clear.
    Our flash contains the following 2 logical sections:
    1. Configuration bitstream (i.e. FPGA image / the bitstream that is loaded into flash at power on)
    2. Our proprietary data (parameters that nios is using during operation, log events, etc.)
    All clear regarding section 1:
    We can use the Design secure feature - AES algorithm modules built in the FPGA.
    Questions regarding section 2:
    Is there an option to use the AES modules, that are already exist inside the FPGA, for encryption/decryption of arbitrary data?
    Do we have access to the AES modules?
