A Dominant Gate Insertion Algorithm Implementation for Logic Locking in IP Protection
I-Chun Tsai, Fang-Ru Liu, Jianhua Feng · 2019
Logic locking manages different logic gates insertion as key-gates along with the key-inputs after location calculation for IP protection. This paper presents a dominant gate algorithm to achieve the security standard of logic locking, which managed the Hamming Distance(HD) exceed 50% while exempt from the key sensitization concurrently. It shows a comprehensive defense ability from the perspective of the general security standard. The results prove that it can simultaneously maintain the mutual interference of the key-inputs and maximize the ambiguity of the output on various benchmark circuits with a reasonable area overhead below 5%.
