摘要： 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.

摘要： A security chip including a fusible logic array. An input is configured to receive, from a verification module external to the security chip, a seed value corresponding to one of a predetermined value and a generated value. The fusible logic array is configured to generate a logic result using the received seed value. The fusible logic array includes a logic gate configured to operate, based on a state of a fusible link within the logic gate, as both a first type of logic gate configured to perform a first logic operation and a second type of logic gate configured to perform a second logic operation different from the first logic operation. The fusible logic array is configured to generate the logic result based on the state of the fusible link. An output is configured to provide a key value, representative of the logic result, to the verification module.

摘要： A system-on-chip including circuit instances, a selector module, a circuit instance module, and a comparing module. The circuit instances have respectively nodes. The circuit instances are designed to provide nominally a same value at each of the nodes. The selector module is configured to generate a selection signal. The circuit instance module is configured to (i) monitor states of the nodes, and (ii) based on the selection signal, select (a) two or more of the states of the nodes, or (b) two or more parameter values generated based on the two or more of the states of the nodes. The comparing module is configured to: compare (i) the two or more of the states of the nodes, or (ii) the two or more parameter values; and based on the comparison, output a bit of (i) a silicon fingerprint of the system-on-chip, or (ii) a unique response code of the system-on-chip.
