IP Protection Using Watermarking with Obfuscation

The technology scaling allows complex systems to be placed on a single die with million transistors integrated into it. Intellectual Property (IP) cores are reusable logic blocks used for building such complicated systems. Secure IP designs that can protect authorship are needed to deter IP piracy. One widely used detection method is digital watermarking which provides proof of the ownership to the IP vendor. The proposed methods in this work can embed into the IP or system obfuscation enabled watermark and also provides techniques for access control and fingerprinting. These techniques were implemented in an 8 bit ALU that can perform 8 operations. The functionality of the system was analyzed using the Xilinx ISE Design suite 14.6.
