An integrated circuit (IC) security apparatus with complementary security traces and a method for producing such an apparatus is disclosed. The security apparatus comprises a pattern generator, and a plurality of security traces. The arrangement of security trace pairs are such that the second trace is arranged substantially parallel to the first trace. The pattern generator produces two signals, a second signal, which is applied to the second trace, is substantially complementary to the first security trace. The timing and amplitude of the second (complementary) signal is developed such that any net induced currents are substantially nulled. One or more of the signals is received from the signal generator and compared to the same signal after it is conducted through a security trace. The results are analyzed to determine if the security of the IC has been breached. |
