Abstract
An exemplary system, method and computer-accessible medium for modifying a design of an integrated circuit(s) (ICs), which can include, for example, modifying a logic gate(s) in the design for a protected input pattern(s), and providing a restoration unit(s) into the design, where the restoration unit(s) can be configured to (i) produce an error-free output(s) when a correct secret key can be applied to the restoration unit(s), and (ii) produce an erroneous output(s) when an incorrect key can be applied to the restoration unit(s); and ensure that the modified design along with the restoration unit produces at least one erroneous output with respect to the original design for only a pre-determined constant number of incorrect keys based on at least one input pattern.
