Arria II Design Security Solution
Arria II devices are SRAM-based devices. To provide design security, Arria II devices
require a 256-bit security key for configuration bitstream encryption.
To carry out secure configuration, follow these steps (refer to
1. Program the security key into the Arria II device.
2. Encrypt the configuration file and store it in the external memory.
3. Configure the Arria II device.
At system power-up, the external memory device sends the encrypted configuration
file to the Arria II device.
Figure 9–29. Design Security
Note to
(1) Step 1, Step 2, and Step 3 correspond to the procedure described in
Program the user-defined 256-bit AES keys to the Arria II device through the JTAG
interface.
Encrypt the configuration file with the same 256-bit keys used to program the
Arria II device. Encryption of the configuration file is done using the Quartus II
software. The encrypted configuration file is then loaded into the external
memory, such as a configuration or flash device.
