在当今竞争激烈的市场中共享IP块会带来很高的安全风险。IP设计的创作者和所有者希望确保他们的内容不会被消费者非法重新分发，消费者希望确保他们购买的内容是合法的。近年来，数字水印技术成为IP数据块版权保护的一种候选方案。在本文中，我们提出了一种新的方法水印IP设计的基础上嵌入的所有权证明的IP设计的有限状态机（FSM）的一部分。该方法利用了设计的状态转换图中的重合和未使用的转换。我们的方法增加了水印的鲁棒性，并允许一个安全的实施，从而使开发的第一个公钥IP水印方案在FSM级别。我们还定义了我们的方法，并使用实验措施来证明其鲁棒性。
Sharing IP blocks in today's competitive market poses significant high security risks. Creators and owners of IP designs want assurances that their content will not be illegally redistributed by consumers, and consumers want assurances that the content they buy is legitimate. Recently, digital watermarking emerged as a candidate solution for copyright protection of IP blocks. In this paper, we propose a new approach for watermarking IP designs based on the embedding of the ownership proof as part of the IP design's finite state machine (FSM). The approach utilizes coinciding as well as unused transitions in the state transition graph of the design. Our approach increases the robustness of the watermark and allows a secure implementation, hence enabling the development of the first public-key IP watermarking scheme at the FSM level. We also define for our approach, and use experimental measures to prove its robustness.
