量子密钥分配的安全性是由量子力学定律而不是计算密码学中未经证明的假设来保证的。不幸的是，密钥速率太低，传输距离有限。后量子密码学（PQC）被提出作为QKD的替代方案。然而，PQC协议是基于猜想，没有多项式时间算法来打破PQC协议。为了克服后量子密码学和QKD的关键挑战，我们建议仅在初始化阶段使用QKD来建立相应的网络安全协议。所提出的概念适用于计算安全和PQC协议。拟议的QKD增强网络安全协议可以容忍量子计算机发起的攻击。
Security of QKD is guaranteed by the quantum mechanics laws rather than unproven assumptions employed in computational cryptography. Unfortunately, the secret-key rates are way too low and transmission distances are limited. The post-quantum cryptography (PQC) is proposed as an alternative to QKD. However, the PQC protocols are based on conjecture that there are no polynomial time algorithms to break the PQC protocols. To overcome key challenges of both post-quantum cryptography and QKD, we propose to use the QKD only in initialization stage to set-up corresponding cybersecurity protocols. The proposed concept is applied to both computational security and PQC protocols. The proposed QKD-enhanced cybersecurity protocols are tolerant to attacks initiated by quantum computers.
