论文摘要
近年来，基于磁性隧道连接（MTJ）的真正随机数发生器（TRNG）变得越来越有吸引力。这是因为基于MTJ的TRNG比传统的基于CMOS的TRNG具有一些优势，例如较小的区域和更简单的结构。但是，迄今为止，尚未有任何工作能够量化基于MTJ的TRNG的原始输出质量，并进行了合适的随机性提取以产生可证明的安全随机位，与基于CMOS的同类产品不同。在这项工作中，我们实现了基于MTJ的TRNG并表征了原始输出的熵。使用此信息，我们执行后处理以提取一组被证明是安全的随机位。
In recent years, true random number generators (TRNGs) based on magnetic tunnelling junction (MTJ) have become increasingly attractive. This is because MTJ-based TRNGs offer some advantages over traditional CMOS-based TRNGs, such as smaller area and simpler structure. However, there has been no work thus far that quantified the quality of the raw output of an MTJ-based TRNG and performed suitable randomness extraction to produce provably-secure random bits, unlike their CMOS-based counterparts. In this work, we implement an MTJ-based TRNG and characterise the entropy of the raw output. Using this information, we perform post-processing to extract a set of random bits which are provably-secure.
