Security Against Tampering
After the Tamper Protection bit is set in the key programming file generated by the
Quartus II software, the Arria II GX device can only be configured with configuration
files encrypted with the same key. Tampering is prevented using both volatile and
non-volatile keys.
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 the key storage to make it more
difficult for anyone to retrieve the stored key using de-capsulation of the device.
Arria II GX devices support two types of security key programming: volatile and
non-volatile.

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