Abstract
In an integrated-circuit chip having intercommunicating modular functional units of electrical circuits, wired transmission of sensitive information signals between the functional units of the electrical circuits involves generating a reference signal and coding the sensitive information signals, after being emitted by a generating functional unit in the chip, with the reference signal to disguise the sensitive information represented by the sensitive information signals. The coded sensitive information signals are decoded with the reference signal before the sensitive information signals are received by a processing functional unit in the chip. At least one signal of the reference signal and the decoded sensitive information signals are monitored, and a hacker attack is identified in response to a determination that the decoded sensitive information signal is other than a plausible signal.
