实现高效的量子密钥分配协调

Toward Efficient Quantum Key Distribution Reconciliation

Nedra Benletaief, Houria Rezig, Ammar Bouallegue

摘要:

在本文中,我们提出了如何构建一个协调的BB84量子密钥分配(QKD)协议的方法。从理论上讲,它是无条件安全的,因为它是基于量子物理定律,而不是假设的数学问题的计算复杂性。BB84协议的性能会因各种错误和信息泄漏而降低,如协议的固有效率有限,不完善的设备和窃听。建议的和解方法允许通过使用Turbo码来消除这些错误。由于它们的高纠错能力意味着得到低错误,所以该方法具有高性能,特别是当与文献中提出的基于低密度奇偶检验码(LDPC)的最后一种方法相比时。特别是,我们证明了我们的方法导致协议的安全性和比特出错率(BER)的显着改善,即使有很大的窃听能力。

英文摘要:

In this paper, we propose how to construct a reconciliation method for the BB84 Quantum Key Distribution (QKD) protocol. Theoretically, it is unconditionally secure because it is based on the quantum laws of physics, rather than the assumed computational complexity of mathematical problems. BB84 protocol performances can be reduced by various errors and information leakages such as limited intrinsic efficiency of the protocol, imperfect devices and eavesdropping. The proposed reconciliation method allowed to weed out these errors by using Turbo codes. Since their high error correction capability implies getting low errors, this method has high performance especially when compared to the last method presented in the literature based on Low- Density Parity Check codes (LDPC). In particular, we demonstrate that our method leads to a significant improvement of the protocol security and of the Bit Error Rate (BER) even with great eavesdropping capability.
