Study on IP protection techniques for integrated circuit in IOT environment

Abstract

The growth of electronic chip technique has led to frequent occurrence of intellectual property (IP) disputes. It seriously affects rapid and healthy development of semiconductor industry. To address the disputes, many IP protection methods are proposed in these years, such as IP watermarking. It is a novel technique to hide secrets in IP core to prove original ownership. This chapter focuses on two issues: how to hide secrets in IP circuit and how to authenticate IP ownership. Four types of IP watermarking methods will be concretely introduced in this chapter. (1) FPGA based IP watermarking technique. (2) FSM based IP watermarking technique. (3) DFT based IP watermarking technique. (4) Self-recoverable dual IP watermarking technique. The experiments show that the proposed schemes have low resource overhead by comparing with other schemes. Meanwhile the resistance to attacks of the watermark is encouraging as well.
