Integrated circuit (IC) camouflaging technique has been applied as a countermeasure against reverse engineering (RE). However, its effectiveness is threatened by a boolean satisfiability (SAT) based de-camouflaging attack, which is able to restore the camouflaged circuit within only minutes. As a de...
