Claim One:
1. A method comprising: computing for one or more inputs of a circuit associated one or more metrics representative of a degree of influence that values of each of the one or more inputs have on at least one output dependent on the one or more inputs, wherein computing for the one or more inputs of the circuit the associated one or more metrics comprises: generating a truth table for the one or more inputs and the at least one output dependent on the one or more inputs, the truth table including at least some combinations of respective input values for the one or more inputs and resultant values of the at least one output dependent on the one or more inputs; and computing for at least one of the one or more inputs, based on the generated truth table, an associated at least one control value representative of a portion of rows of the truth table whose output is influenced by the at least one of the one or more inputs; and determining based, at least in part, on the computed one or more metrics associated with the one or more inputs whether the at least one output dependent on the one or more inputs is part of a potentially malicious implementation.
