摘要

提出了一种基于HDL设计的IP核知识产权保护(IPP)水印技术。其基本思想依赖于在HDL设计级别使用原始系统中包含的组合逻辑或查找结构来扩展数字签名的位。这些技术还包括一个安全和非破坏性的签名提取过程。此外,在这项工作中,由于开发了用于签名传播目的的自动化工具,其适用性得到了扩展。自动化工具的进步是通过包含新的搜索算法来实现的,例如模拟退火算法,它在减少计算时间的同时实现了额外的资源优化。为了显示在设计努力、额外资源和执行时间方面的优势,对研究算法进行了详细的研究。

Intellectual Property Protection of IP Cores at HDL Design Level with Automatic Signature Spreading
Watermarking techniques for Intellectual Property Protection (IPP) of IP cores at the HDL design level are proposed in this paper. The basic idea relies on spreading the bits of a digital signature at the HDL design level using combinational logic or look-up structures included within the original system. The techniques also include a secure and non-destructive signature extraction process. Furthermore, in this work the applicability has been extended due to the development of an automated tool for signature spreading purposes. Advances in the automated tool have been achieved by including new search algorithms, as the Simulated Annealing algorithm that achieves additional resources optimization while maintains reduced computation times. A detailed study of the research algorithms is carried out in order to show the advantages in terms of design effort, additional resources and execution times.
