As described in the Boot Time Security, FPGA-only devices also need to maintain security while deploying them in the field. Xilinx® tools provide embedded IP modules to achieve the Encryption and Authentication, is part of programming logic. Bootgen extends the secure image creation (Encrypted and/or Authenticated) support for FPGA family devices from 7 series and beyond. This chapter details some of the examples of how Bootgen can be used to encrypt and authenticate a bitstream. Bootgen support for FPGAs is available in the standalone Bootgen install.
Note: Only bitstreams from 7 series devices and beyond are supported.
