Securing Hardware Designs Against Unauthorized Use and Overproduction Through Polymorphic Switch Boxes and Security-Aware High-Level Synthesis

This paper presents an interconnect obfuscation methodology at the Register-Transfer Level (RTL) using Switch Boxes (SBs) constructed of Polymorphic Transistors to protect integrated circuit designs from unauthorized use and illegal overproduction. Security-aware high-level synthesis algorithms are also introduced to strategically assign RTL interconnects to functional units in a way that corrupts multiple outputs when the polymorphic SBs are incorrectly unlocked.
