IP core and integrated circuit protection using robust watermarking

This chapter discusses robust watermarking approaches for the ownership protection of hardware cores [a.k.a. intellectual property (IP) cores]. Watermarking ensures some additional attributes inserted in the hardware core such a way that it can be used to verify ownership of the hardware core when required. Robust watermarking approaches have been discussed as these are resilient to various attacks that happen in global supply chain for various reasons.
