摘　　要：通过对信号传输理论、竞争-冒险现象和物理不可克隆函数(Physical Unclonable Functions,PUF)电路的研究,论文提出一种基于信号传输理论的"毛刺"型物理不可克隆函数电路(Glitch Physical Unclonable Functions,Glitch-PUF)方案。该方案首先根据偏差延迟的信号传输理论,推导出获得稳定"毛刺"输出的电路级数;然后利用组合逻辑电路的传播延迟差异,结合"1"冒险和"0"冒险获得具有"毛刺"的输出波形,采用多级延迟采样电路实现Glitch-PUF的输出响应。由于"毛刺"信号具有显著的非线性特性,将其应用于PUF电路可有效解决模型攻击等问题。最后在TSMC 65 nm CMOS工艺下,设计128位数据输出的电路结构,Monte Carlo仿真结果表明Glitch-PUF电路具有良好的随机性。In this paper, a Glitch-PUF circuit technique is proposed by taking into consideration various aspects i.e. the signal transmission theory, race and hazard phenomenon, and Physical Unclonable ~nctions （PUF）. First and foremost, the glitch circuit is obtained under the signal transmission theory. Using the combinational logic circuit propagation delay difference which causes 1-hazard and 0-hazard, this feature is used to form output glitch waveform. This glitch is sampled by multistage delay sampling circuit. Due to the nonlinear characteristics of the Glitch, Glitch-PUF can thwart the modeling attack. Finally, under the TSMC 65 nm CMOS technology, a 128-bit output data Glitch-PUF circuit is designed. Monte Carlo simulation results show that the Glitch PUF circuit has better randomness.
