An Efficient Communication Protocol for FPGA IP Protection

We introduce a protection-based IP security scheme to protect soft and firm IP cores which are used on FPGA devices. The scheme is based on Finite State Machin (FSM) obfuscation and exploits Physical Unclonable Function (PUF) for FPGA unique identification (ID) generation which help pay-per-device licensing. We introduce a communication protocol to protect the rights of parties in this market. On standard benchmark circuits, the experimental results show that our scheme is secure, attack-resilient and can be implemented with low area, power and delay overheads.
