Experimental Demonstration of Security Evaluation via Hamming Distance in Quantum Noise Stream Cipher
Bo Wang, Yajie Li, Chao Lei, Kongni Zhu, Yongli Zhao, Jie Zhang · 2021
We introduce the metric of fractional Hamming distance to evaluate the security of quantum noise cipher system. Experimental results show that this metric is helpful to analysis and measurement in practical communications with finite-block lengths.
