量子密码学提供了一个有前途的牢不可破的密码解决方案，因为它确保了量子密钥分配和比特承诺等应用的完美保密性。本文的重点是跟踪量子密钥分配协议的发展，并讨论了在这一领域的最新技术和开放的问题。虽然这些协议在数学上被证明是完全安全的，但必须强调的是，任何真实的世界的实现都受到物理设备的限制，这些物理设备可以作为窃听者利用的漏洞。在本文中，我们调查了文献中存在的量子密钥分配协议，并探讨了它们容易受到的攻击。我们强调了与每个实施相关的主要实施瓶颈及其提出的解决方案。
Quantum cryptography offers a promising unbreakable cryptographic solution as it ensures perfect secrecy in applications such as quantum key distribution and bit commitment. The focus of this paper is to trace the development of quantum key distribution protocols and discuss the state of the art and open issues in this field. Although the protocols have mathematically proven to be totally secure, it must be emphasized that any real world implementation suffers the limitations of physical devices which can serve as vulnerability for an eavesdropper to exploit. In this paper, we survey the quantum key distribution protocols which exist in literature and explore the attacks to which they are vulnerable. We highlight the main implementation bottlenecks related with each implementation and the solutions proposed thereof.
