Title
Keynote: A Disquisition on Logic Locking
Abstract
The fabless business model has given rise to many security threats, including piracy of intellectual property (IP), overproduction, counterfeiting, reverse engineering (RE), and hardware Trojans (HT). Such threats severely undermine the benefits of the fabless model. Among the countermeasures developed to thwart piracy and RE attacks, <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">logic locking</italic> has emerged as a promising and versatile solution that is being adopted by both academia and industry. The idea behind logic locking is to lock the design using a “keying” mechanism; only the rightful owner has control over the locked design. Therefore, the design remains nonfunctional without the knowledge of the key. In this article, we survey the evolution of logic locking over the last decade. We introduce various “cat-and-mouse” games involved in logic locking along with its novel applications—including, processor pipelines, graphics processing units (GPUs), and analog circuits. We aim this article to be a primer for researchers interested in developing new logic-locking techniques and employing logic locking in different application domains.
