Abstract:
1. A design structure embodied in a machine readable storage medium used in a design process, the design structure comprising a circuit that employs an anti-tamper sensor, the circuit including: a. a circuit element that is responsive to a first input and to a second input; b. a selective coupling element that couples the circuit element to the first input, the first selective coupling element responsive to the anti-tamper sensor and having a first state that allows the circuit element to operate normally when the anti-tamper sensor does not detect a tamper condition, the first selective coupling element also configured to enter a second state that causes the circuit element to become inoperable when the anti-tamper sensor detects a tamper condition; and c. a decoy coupling element that is disposed between the second input and the circuit element and that has an appearance corresponding to the selective coupling element but that will cause the circuit element not to operate normally if the decoy coupling element has a selected physical property of the selective coupling element in the first state.
