基于类Johnson噪声Kirchhoff环的2 ~ 2000公里距离的经典安全特性
Johnson(-like)-Noise-Kirchhoff-Loop Based Secure Classical Communicator Characteristics, for Ranges of Two to Two Thousand Kilometers, via Model-Line
摘要:
设计并制造了一对能够在可变范围内工作的Kirchhoff-Loop-Johnson(类)噪声通信器。已经对模型线性能特性进行了测试,其范围超出了任何已知的直接量子通信信道的范围,并且它们表明交换的原始密钥比特的无与伦比的信号保真度和安全性能。这种简单的设备对于21 mm / 2000 km、7 mm / 200 km、2.3 mm / 20 km和0.7 mm / 2 km的相应铜线直径/范围具有0.1、1、10和100比特/秒的单线安全密钥生成和共享速率,并且其以0.02%的原始比特错误率(99.98%的保真度)执行。这个实际系统的原始比特安全性明显优于原始比特量子安全性。电流注入中断测试显示零比特窃听能力而不触发警报信号,因此不需要多个测量来建立错误统计来检测量子通信中的窃听。Bergou-Scheuer-Yariv类型的基于导线电阻的断裂测试给出窃听的原始比特率的上限为0.19%,并且该极限与电缆直径的六次方成反比。Hao的破坏方法产生零(低于测量分辨率)窃听信息。
英文摘要:
A pair of Kirchhoff-Loop-Johnson(-like)-Noise communicators, which is able to work over variable ranges, was designed and built. Tests have been carried out on a model-line performance characteristics were obtained for ranges beyond the ranges of any known direct quantum communication channel and they indicate unrivalled signal fidelity and security performance of the exchanged raw key bits. This simple device has single-wire secure key generation and sharing rates of 0.1, 1, 10, and 100 bit/second for corresponding copper wire diameters/ranges of 21 mm / 2000 km, 7 mm / 200 km, 2.3 mm / 20 km, and 0.7 mm / 2 km, respectively and it performs with 0.02% raw-bit error rate (99.98 % fidelity). The raw-bit security of this practical system significantly outperforms raw-bit quantum security. Current injection breaking tests show zero bit eavesdropping ability without triggering the alarm signal, therefore no multiple measurements are needed to build an error statistics to detect the eavesdropping as in quantum communication. Wire resistance based breaking tests of Bergou-Scheuer-Yariv type give an upper limit of eavesdropped raw bit ratio of 0.19 % and this limit is inversely proportional to the sixth power of cable diameter. Hao's breaking method yields zero (below measurement resolution) eavesdropping information.
