摘　　要：提出了一种基于物理不可克隆函数(PUF)的硬件辅助软件认证方法,包括软硬件认证协议、嵌入PUF的RISC-V设计、软件混淆技术三部分,通过插入独立式PUF认证点或嵌入式PUF认证点,将软件与硬件绑定在一起,软件仅在特定的授权设备上才能正确执行,并从硬件和软件层面解决了PUF可靠性的问题。实验结果表明,所提方法的额外硬件开销小于2%,基准程序测试结果表明单个认证点的额外性能开销小于0.5%。A hardware-assisted software authentication method based on PUF was proposed.It included software and hardware authentication protocol,RISC-V design embedded in PUF,and software obfuscation technology.The software and hardware were bound together by inserting independent PUF authentication points or embedded PUF authentication points.The software could only be executed correctly on a specific authorized device,and the reliability of PUF was solved from the hardware and software level.Experiments showed that the additional hardware overhead of the proposed method was less than 2%;and the benchmark test showed that the additional performance overhead of a single authentication point was less than 0.5%.
