论文摘要
我们提出了针对强大PUF的安全且基于重量的钥匙挑战。我们的架构旨在抵抗学习攻击。我们的混淆机制使用非线性反馈移位寄存器（NLFSR）。响应直接向用户提供，而无需纠正错误或额外的后处理步骤。我们还讨论了通过时钟随机化和布尔掩蔽保护我们的体系结构免受电源分析攻击的成本。使用雪崩标准和深神经网络攻击评估了对学习攻击的安全性。我们在65 nm CMOS中设计了一个测试笑。与基线仲裁者PUF实施相比，我们所提出的体系结构的成本增加为1.27倍，使用时钟随机化和布尔屏蔽分别为2.2倍。
We propose a secure and lightweight key based challenge obfuscation for strong PUFs. Our architecture is designed to be resilient against learning attacks. Our obfuscation mechanism uses non-linear feedback shift registers (NLFSRs). Responses are directly provided to the user, without error correction or extra post-processing steps. We also discuss the cost of protecting our architecture against power analysis attacks with clock randomization, and Boolean masking. Security against learning attacks is assessed using avalanche criterion, and deep-neural network attacks. We designed a testchip in 65 nm CMOS. When compared to the baseline arbiter PUF implementation, the cost increase of our proposed architecture is 1.27x, and 2.2x when using clock randomization, and Boolean masking, respectively.
