用LDPC码构造BB84量子密钥分发协议的CSS码

Constructing CSS Codes with LDPC Codes for the BB84 Quantum Key Distribution Protocol

Maki Ohata, Kanta Matsuura

摘要:

本文提出了一种简单的构造用于BB84量子密钥分发协议的线性码对的方法。该协议允许在存在窃听者的情况下的无条件安全性,并且该对线性码用于纠错和隐私放大。由于它们的高译码性能意味着低的窃听者的互信息,这两个码的良好的设计是必需的。该方法允许使用任意低密度奇偶校验(LDPC)码。因此,它具有低复杂度和高性能的硬件实现。仿真结果表明,这对码对在实际和各种噪声水平下都有很好的性能。

英文摘要:

In this paper, we propose how to simply construct a pair of linear codes for the BB84 quantum key distribution protocol. This protocol allows unconditional security in the presence of an eavesdropper, and the pair of linear codes is used for error correction and privacy amplification. Since their high decoding performance implies low eavesdropper's mutual information, good design of the two codes is required. The proposed method admits using arbitrary low-density parity-check (LDPC) codes. Therefore, it has low complexity and high performance for hardware implementation. Simulation results show that the pair of codes performs well against practical and various noise levels.
