介绍了物理真随机数的需求,对比了物理真随机数和伪随机数的区别,总结了国内外物理真随机数的研究进展。特别地,给出了利用激光器进行物理真随机数发生器研制的多种方案。最后对本小组近年来在理论和实验方面的研究成果进行了总结性的介绍。
The requirement of physical true random number generator and the difference between the true random number and pseudo-random number are presented. The recent experiements of true ran- dom number generator, expetically, the various schemes of true random number generator based on lasers, are summarized. Also, we report the progress of the thoretical and experimental research on physical true random number generator in our group.
