Hardware IP Protection through Provably Secure State-Space Obfuscation

Faculty:Swarup Bhunia
Project Description:Hardware intellectual property (IP) cores are the most essential part of the system- on-chip (SoC) design flow. IPs are vulnerable to a numerous threat which makes it difficult for the IP vendors to prevent piracy of their IPs. We propose a novel, scalable, and considerable overhead methodology to provide effective prevention against IP piracy by netlist level obfuscation. We transform the underlying finite state machine of the design to insert authentication mechanism and expand the state space which in general is small and prune to state traversal. Due to the expansion of the state space and insertion of authentication mechanism, it becomes difficult for an attacker to traverse the state space which essentially makes the design resilient to piracy.
