摘要
超晶格是一种新型PUF实现技术,具有物理不可克隆的孪生现象,基于这个现象可以实现异地之间的密钥分发。对超晶格进行温度特性研究实验和温度控制设计。研究结果表明超晶格室温25℃下片内汉明距离为3.39%,温度每变化4℃片内汉明距离上升4%左右,不利于超晶格实际环境中的应用。根据实验结果设计温控系统提高超晶格的温度适用范围,在不影响超晶格正常工作情况下,-20℃~45℃温度范围内保证超晶格的输出端响应信号片内汉明距离波动控制在6%以下。
Superlattice as a new Physical Unclonable Function(PUF)technology can realize key distribution between different places due to its physically unclonable twin phenomenon.The temperature characteristic of the superlattice PUF has been reported.The hamming distance between superlattice PUF is 3.39%at room temperature and increases by 4%for every 4℃temperature change which is not conducive to the application of superlattice in the actual environment.Moreover,a temperature control system has been designed to increase the temperature application range of the superlattice.The control system makes the hamming distance fluctuation of the superlattice below 6%within the temperature range of-20℃~45℃without any affection for the normal working condition of the superlattice.
