Abstract: An emission map of a circuit to be tested for alterations is obtained by measuring the physical circuit to be tested. An emission map of a reference circuit is obtained by measuring a physical reference circuit or by simulating the emissions expected from the reference circuit. The emission map of the circuit to be tested is compared with the emission map of the reference circuit, to determine presence of alterations in the circuit to be tested, as compared to the reference circuit.
