I'am using 2070 serie Zynq with linux with a project. Some of PL codes which should be protected are loaded partially at runtime. I have a couple of guestions. Thanks in advance.
Security is a fairly important issue for the project. As I have understood till now from the documents I can read the code back somehow. As yet I didn't use the aes engine provided in Zynq, but I'm planning. If I use encrypted configuration or not, in both case I can read the plain configuration (unencrypted), right?
The second question is that: The encryption key has a fuse to prevent to read back. Why there is no a fuse mechanism for configuration code and will Xilinx do it in later times (or verisons)?

Thank you for reply and precious information.
Ok, I cannot read the configuration from JTAG interface provided that the code is encrypted - that is also important-, but I am not sure whether I can read PS's programming port (via PCAP) by a software.I mean that when I get a third party encrypted configuration code, I can read it unauthorizedly, moreover wth unencrypted condition. That's what I don't want to do.
