英文摘要：

Based on the study the timing deviation of monostable circuit and physical unclonable function （PUF） circuit, a high recognition PUF circuit scheme was proposed. Firstly, by analyzing the self identity physical properties of monostable circuit, a long-range timing design method was presented. The monostable circuit is then used to generate a timing deviation signal, and two timing deviation signals were chosen by multiplexer through challenge signal. The arbiter circuit determined high recognition and unclonable response. The proposed PUF circuit was simulated under TSMC 65 nm CMOS technology by Monte Carlo test. With the Monte Carlo simulation results, its u- niqueness and reliability under different circumstances were analyzed. Experimental results show that the recognition rate of PUF circuit is 99.82% with bit error rate of 2.7%.
