量子密钥分发中基于GMP的高速保密放大方案

High-speed Privacy Amplification Scheme using GMP in Quantum Key Distribution

Bingze Yan, Haokun Mao, Xiaofeng Xue, Qiong Li

摘要:

隐私放大(PA)是一种通过公开讨论从部分安全的字符串中提取高度机密的密钥的技术。产生理论上无条件安全的密钥是量子密钥分发(QKD)中的一个重要环节。PA的吞吐量已成为高速离散变量量子密钥分配(DV-QKD)系统的瓶颈。提出了一种基于GNU多精度(GMP)算法库的高速模算术散列PA方案。该方案在两个不同的中央处理器(CPU)平台上实现。实验结果表明,在块大小为10^6时,该方案的吞吐量达到260 Mbps,在块大小为10^8时,该方案的吞吐量达到140 Mbps。据作者所知,这是目前在CPU平台上实现的最快的录波方案。

英文摘要:

Privacy amplification (PA) is the art of distilling a highly secret key from a partially secure string by public discussion. It is a vital procedure in quantum key distribution (QKD) to produce a theoretically unconditional secure key. The throughput of PA has become a bottleneck of the high-speed discrete variable QKD (DV-QKD) system. In this paper, a high-speed modular arithmetic hash PA scheme with GNU multiple precision (GMP) arithmetic library is presented. This scheme is implemented on two different central processing unit (CPU) platforms. The experimental results demon-strate that the throughput of this scheme achieves 260Mbps on the block size of 10^6 and 140Mbps on the block size of 10^8. This is the highest-speed recorded PA scheme on CPU platform to the author's knowledge.
