Fragile IP Watermarking Techniques (original) (raw)

Constraint-based watermarking techniques for design IP protection

2001

Abstract Digital system designs are the product of valuable effort and know-how. Their embodiments, from software and hardware description language program down to device-level netlist and mask data, represent carefully guarded intellectual property (IP). Hence, design methodologies based on IP reuse require new mechanisms to protect the rights of IP producers and owners.

Rethinking Watermark: Providing Proof of IP Ownership in Modern SoCs

IACR Cryptol. ePrint Arch., 2022

Intellectual property (IP) cores are essential to creating modern system-on-chips (SoCs). Protecting the IPs deployed in modern SoCs has become more difficult as the IP houses have been established across the globe over the past three decades. The threat posed by IP piracy and overuse has been a topic of research for the past decade or so and has led to creation of a field called watermarking. IP watermarking aims of detecting unauthorized IP usage by embedding excess, nonfunctional circuitry into the SoC. Unfortunately, prior work has been built upon assumptions that cannot be met within the modern SoC design and verification processes. In this paper, we first provide an extensive overview of the current state-of-the-art IP watermarking. Then, we challenge these dated assumptions and propose a new path for future effective IP watermarking approaches suitable for today’s complex SoCs in which IPs are deeply embedded.

Robust IP watermarking methodologies for physical design

1998

Abstract Increasingly popular reuse-based design paradigms create a pressing need for authorship enforcement techniques that protect the intellectual property rights of designers. We develop the first intellectual property protection protocols for embedding design watermarks at the physical design level.
