基于CHIP ID的FPGA加密算法设计与实现

Design and implementation of FPGA encryption algorithm based on CHIP ID

针对FPGA芯片上电配置数据容易被窃取的问题,提出了一种基于CHIP ID的加密算法。CHIP ID是Altera公司Cyclone V系列FPGA,出厂就带有的唯一ID,调用IP核就可以读出每个芯片的ID。此ID可以根据开发者的需求加入个性化加密算法并与指定FPGA结合起来,生成配置比特流文件。主程序运行自定义加密算法计算出一个加密值,将加密值与预存的匹配值进行对比,判断程序是否正常运行。结果表明使用CHIP ID加密的方法具有稳定高效、简单可靠和资源占用少等优点。

Aiming at the problem that FPGA chip power-on configuration data is easily stolen,an encryption algorithm based on CHIP ID is proposed.CHIP ID is the unique ID that comes with Altera′s Cyclone V series FPGAs.Each CHIP ID can be read by calling the IP core,this ID can be added to the personalized encryption algorithm according to the needs of developers and combined with the specified FPGA to generate configuration bitstream files.The main program runs a custom encryption algorithm to calculate an encrypted value,compares the encrypted value with the pre-stored matching value,and judges whether the program is running normally.The results show that the method using CHIP ID hardware encryption has the advantages of high-stability,high-efficiency,high-reliability,and less resource occupation.
