论文摘要
本文介绍了对称的可扩展量子秘密共享协议，这是一种用于秘密共享的新型量子协议。它的核心是基于纠缠的协议，它依赖于使用最大纠缠的GHz元组，在玩家之间均匀分布，使Spymaster赋予了与她的代理商安全共享秘密信息的能力。它提供了毫不妥协的安全性，使恶意的窃听者或流氓双重代理商破坏其成功的执行几乎是不可能的。它的特征是对称性，因为所有试剂均使用相同的量子电路进行了不加选择的处理。此外，它可以无缝扩展到任意数量的代理。协议的量子部分完成后，Spymaster必须公开传输一些信息，以使代理商能够发现秘密消息。最后，它具有额外的优势，即Spymaster有特权决定何时是代理商发现秘密消息的合适时机。
This paper introduces the Symmetric Extensible Quantum Secret Sharing protocol, which is a novel quantum protocol for secret sharing. At its heart, it is an entanglement based protocol that relies on the use of maximally entangled GHZ tuples, evenly distributed among the players, endowing the spymaster with the ability to securely share a secret message with her agents. It offers uncompromising security, making virtually impossible for a malicious eavesdropper or a rogue double agent to disrupt its successful execution. It is characterized by symmetry, since all agents are treated indiscriminately, utilizing identical quantum circuits. Furthermore, it can be seamlessly extended to an arbitrary number of agents. After the completion of the quantum part of the protocol, the spymaster will have to publicly transmit some information, in order to enable the agents to discover the secret message. Finally, it has the additional advantage that the spymaster has the privilege to decide when it is the right time for the agents to discover the secret message.
