无厂房商业模式带来了许多安全威胁，包括盗版知识产权(IP)、生产过剩、假冒、逆向工程(RE)和硬件特洛伊木马(HT)。这种威胁严重破坏了无厂房模式的好处。在为阻止盗版和RE攻击而开发的对策中，逻辑锁定已成为学术界和工业界都正在采用的一种有前途的通用解决方案。逻辑锁定背后的思想是使用“键控”机制锁定设计；只有合法的所有者才能控制锁定的设计。因此，在不知道密钥的情况下，设计仍然不起作用。在本文中，我们回顾了逻辑锁定在过去十年中的发展。我们介绍了逻辑锁定所涉及的各种“猫和老鼠”游戏及其新颖的应用--包括处理器流水线、图形处理单元(GPU)和模拟电路。本文旨在为对开发新的逻辑锁定技术和在不同应用领域中使用逻辑锁定感兴趣的研究人员提供入门读物。
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, logic locking 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.
