我们展示了一种方法，信息理论的安全密钥生成的基础上，从一个快速波动的随机信号产生的混沌半导体激光器和光纤传输的连续数据采集的实际物理限制。用户独立随机地抓取混沌波形的片段，分成标签部分和密钥部分，并交换标签部分以识别可用于制作安全密钥的公共密钥部分。波形中的触发脉冲的频率用于控制该方案的安全性，该方案依赖于第三方巧合地获取由另外两个用户获取的样本的小概率。
We demonstrate a method for information theoretic secure key generation based on practical physical limits of continuous data acquisition from a rapidly fluctuating random signal generated by a chaotic semiconductor laser and transmitted over an optical fiber. Users independently and randomly grab sections of the chaotic waveform, separate into tag and key parts, and exchange tag parts to identify the common key parts which can be used to make secure keys. The frequency of trigger pulses in the waveform is used to control the security of the scheme which depends on the small probability of a third party coincidentally acquiring samples acquired by two other users.
