description A security chip including a fusible logic array. The fusible logic array is configured to receive a plurality of seed values and output a plurality of respective keys using the received plurality of seed values. The respective keys correspond to logic results generated by the fusible logic array. The fusible logic array includes one or more fusible links. A key storage control module is configured to receive the plurality of seed values, receive the plurality of respective keys, and store, in memory, a selected first seed value of the plurality of seed values and a selected first key of the plurality of respective keys. The selected first seed value and the selected first key are stored as a seed-key pair.
