This application note guides a user on how to use the PUF’s device-unique encryption key in
conjunction with the AES-GCM hardware in order to encrypt user generated data and store the
encrypted data externally. The encrypted data can then be read from external storage and
decrypted using the AES-GCM hardware in conjunction with the PUF’s device-unique key. In
addition, this application note shows how to perform data validation of decrypted data packets
by utilizing values stored in the user programmable section of eFUSEs.
