Programming the AES Encryption Key
The FPGA device provides both volatile and non-volatile key storage. After the encryption key is generated, you store the key, as described in "Creating an Encrypted Second-State Boot Loader Image". The key is later referenced by the AES-based algorithms that decrypt the boot image. See the "AES Decryption" figure in "AES Encryption and Decryption".
