基于FPGA的IP核水印保护方法

A Watermark Protecting Method for IP Core Based on FPGA

随着FPGA在容量、功能和灵活性等方面的不断提高,越来越多IP核以其为基础进行设计,然而基于FPGA的IP核易被第三方窃取并进行非法扩散。通过将用户身份信息作为水印嵌入FPGA,以达到保护IP核安全,防止非法扩散的目的。

With the great improvement in capacity, functionality and flexibility, FPGAs are widely used to implement various IP cores. That are, however, very hkely to be stolen and spread by illegal third part. In this paper, we proposed a new approach to embed the owner＇s signature as watermark to FPGA, so the security of IP core can be assured, and the illegal distribution can be prevented.
