Paper Abstract

This paper presents significant improvements to our previous watermarking technique for Intellectual Property Protection (IPP) of IP cores. The technique relies on hosting the bits of a digital signature at the HDL design level using resources included within the original system. Thus, any attack trying to change or remove the digital signature will damage the design. The technique also includes a procedure for secure signature extraction requiring minimal modifications to the system. The new advances refer to increasing the applicability of this watermarking technique to any design, not only to those including look-ups, and the provision of an automatic tool for signature hosting purposes. Synthesis results show that the application of the proposed watermarking strategy results in negligible degradation of system performance and very low area penalties and that the use of the automated tool, in addition to easy the signature hosting, leads to reduced area penalties.
