Reverse engineering from an encrypted configuration file is very difficult and time
consuming because the Stratix III configuration file formats are proprietary and the
file contains million of bits which require specific decryption. Reverse engineering the
Stratix III device is just as difficult because the device is manufactured on the most
advanced 65-nm process technology.
The non-volatile keys are one-time programmable. Once the tamper protection bit is
set in the key programming file generated by the Quartus
device can only be configured with configuration files encrypted with the same key.
For more information about why this feature is secured, refer to the
Stratix III Devices
The main purpose of the AES decryption block is to decrypt the configuration
bitstream prior to entering data decompression or configuration.
Prior to receiving encrypted data, you must enter and store the 256-bit security key in
the device. You can choose between a non-volatile security key and a volatile security
key with battery backup.
The security key is scrambled prior to storing it in key storage in order to make it
more difficult for anyone to retrieve the stored key using de-capsulation of the device.
Stratix III devices support two types of security key programming: volatile and
non-volatile.

You can program the non-volatile key to the Stratix III device without an external
battery. Also, there are no additional requirements to any of the Stratix III power
supply inputs.
