摘要
针对目前保密放大方案存在的随机种子使用量大的问题,提出了一种基于模块化广义Trevisan随机提取器结构的量子密钥分配(QKD)保密放大的设计方案,并借助量子边信息分析理论,给出了该方案的安全性证明。结果表明,该方案不仅能够抵抗量子攻击,而且能有效节约随机种子,实现可扩展的高效保密放大。
Abstract
In consideration of the problem of the large usage of random seeds in the current privacy amplification schemes, one design scheme of privacy amplification in quantum key distribution (QKD) based on modular and generalized Trevisan’s randomness extractor construction is proposed, and the confirmation of its security with the help of quantum side information analysis theory is presented. The results indicate that such a scheme not only resists against quantum attacks but also effectively reduces the usage of random seeds to ensure an efficient and malleable privacy amplification.
