【摘要】：針對仲裁器物理不可克隆函數(shù)(PUF)響應(yīng)隨機性難以保證的問題,提出具有內(nèi)建自調(diào)整功能的仲裁器PUF設(shè)計,該設(shè)計包含激勵產(chǎn)生模塊、可調(diào)仲裁器PUF模塊和自調(diào)整模塊.首先在傳統(tǒng)仲裁器PUF上增加由調(diào)整信號控制的時延調(diào)節(jié)電路,實現(xiàn)可調(diào)仲裁器PUF結(jié)構(gòu);然后用線性反饋移位寄存器實現(xiàn)激勵產(chǎn)生模塊,生成用于測試PUF隨機性的激勵;最后加入自調(diào)整模塊,通過分析PUF響應(yīng)的隨機性自動調(diào)整時延調(diào)節(jié)電路的調(diào)整信號,提高可調(diào)仲裁器PUF的隨機性.實驗結(jié)果表明,經(jīng)過自調(diào)整,在FPGA上實現(xiàn)的多個所提仲裁器PUF,其隨機性的平均值為50.62%,標(biāo)準(zhǔn)差僅為0.5%,隨機性得到有效提高.
[Abstract]:In order to solve the problem that the randomness of the physical non-clone function of the arbiter is difficult to guarantee, a design of PUF with built-in self-adjustment function is proposed. The design includes excitation generation module, adjustable arbiter PUF module and self-adjusting module. Firstly, a time-delay adjusting circuit controlled by adjusting signal is added to the traditional arbiter PUF to realize the adjustable arbiter PUF structure, and then the excitation generation module is realized by linear feedback shift register, which is used to test the randomness of PUF. Finally, a self-adjusting module is added to improve the randomness of the adjustable arbiter PUF by analyzing the randomness of the PUF response and automatically adjusting the signal of the time-delay adjusting circuit. The experimental results show that the average randomness of the proposed arbiters implemented on FPGA is 50.62, the standard deviation is only 0.5, and the randomness is improved effectively.
