Description

Is there a way to change the AES encryption key remotely in a field deployed system?

Solution

Yes. You can add the capability to play an ACE file, refer to the "Embedded JTAG ACE Player" Application Note (XAPP424):

http://www.xilinx.com/bvdocs/appnotes/xapp424.pdf.

You can create a new AES Key using iMPACT and the resulting ACE file implemented by the JTAG Player in the embedded system.
