You can use the design security feature with other configuration features, such as the
compression and remote system upgrade features. When you use compression with
the design security feature, the configuration file is first compressed and then
encrypted using the Quartus II software. During configuration, the Arria II device
first decrypts and then decompresses the configuration file.
