VLSI Design IP Protection: Solutions, New Challenges, and Opportunities

It has been a decade since the need of VLSI design intellectual property (IP) protection was identified. The goals of IP protection are: 1) to enable IP providers to protect their IPs against unauthorized use, 2) to protect all types of design data used to produce and deliver IPs, 3) to detect the use of IPs, and 4) to trace the use of IPs. There are significant advances from both industry and academic towards these goals. However, do we have solutions to achieve all these goals? What are the current state-of-the-art IP protection techniques? Do they meet the protection requirement designers sought for? What are the (new) challenges and is there any feasible answer to them in the foreseeable future? This paper addresses these questions and provides possible solutions mainly from academia point of view. Several successful industry practice and ongoing efforts are also discussed briefly
