论文摘要
在这项工作中，我们考虑以下问题：给定间谍网络，所有这些都分布在太空中的不同位置，并假设每个间谍都拥有一个很小但不完整的大秘密的一部分，是否有可能将所有这些部分秘密安全地将所有这些部分秘密安全地传递给Spymaster，以便可以将它们组合在一起以揭示大秘密？我们将其称为量子秘密聚合问题，我们以量子游戏的形式提出了一个协议，而爱丽丝接管了Spymaster的角色，该协议以完全的通用性解决了这个问题。我们的协议依赖于最大纠缠的GHz元素的使用，该元素对称分布在爱丽丝及其所有间谍之间。纠缠的力量使从代理商到Spymaster的小部分秘密的安全传播成为可能。作为额外的奖金，纠缠通过使臭名昭著的窃听前夕窃取大秘密的统计学不可能，保证了协议的安全性。
In this work we consider the following problem: given a network of spies, all distributed in different locations in space, and assuming that each spy possesses a small, but incomplete by itself part of a big secret, is it possible to securely transmit all these partial secrets to the spymaster, so that they can be combined together in order to reveal the big secret? We refer to it as the Quantum Secret Aggregation problem, and we propose a protocol, in the form of a quantum game, with Alice taking over the role of the spymaster, that addresses this problem in complete generality. Our protocol relies on the use of maximally entangled GHZ tuples, which are symmetrically distributed among Alice and all her spies. It is the power of entanglement that makes possible the secure transmission of the small partial secrets from the agents to the spymaster. As an additional bonus, entanglement guarantees the security of the protocol, by making it statistically improbable for the notorious eavesdropper Eve to steal the big secret.
