Watermarking techniques for Intellectual Property Protection (IPP) of IP cores at the HDL design level are proposed in this paper. The basic idea relies on spreading the bits of a digital signature at the HDL design level using combinational logic or look-up structures included within the original system. The techniques also include a secure and non-destructive signature extraction process. Furthermore,...
This paper presents significant improvements to 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. The technique also includes a procedure for secure signature extraction requiring minimal modifications to the system. The...
This paper presents significant improvements to our previous watermarking technique for Intellectual Property Protection (IPP) that enables the protection of IP cores. The technique relies on hosting the bits of a digital signature at the HDL design level using combinational logic included within the original system. Thus, any attack trying to change or remove the digital signature will damage the...
In this paper, a procedure for intellectual property protection (IPP) of digital circuits called IPP@HDL is presented. Its aim is to protect the author rights in the development and distribution of reusable modules by means of an electronic signature. The technique relies on hosting the bits of the digital signature within memory structures or combinational logic that are part of the system, at the...
This paper presents a technique for intellectual property protection (IPP) of systems to be implemented over programmable devices. The aim is to protect the author rights of reusable IP cores by means of a digital signature that uniquely identifies both the original design and the design recipient. The technique relies on a procedure that spreads a digital signature in cells of look-up tables of designs...
This paper presents a watermarking technique for intellectual property protection (IPP) of circuits based on the residue number system (RNS). This technique relies on embedding a digital signature in non used cells of look-up tables of RNS-based designs at HDL design level; this enables the protection of author rights in the development and distribution of these designs as reusable modules (IP cores)...
