量子信息的多方数据隐藏

Multiparty data hiding of quantum information

Patrick Hayden, Debbie Leung, Graeme Smith

摘要:

我们提出的协议,多方数据隐藏的量子信息,实现所有可能的阈值访问结构。与秘密共享密切相关,数据隐藏具有更苛刻的安全要求:数据保持安全,免受无限制的LOCC攻击。在隐藏大量数据的限制下,我们的协议实现了每个本地物理量子比特一个隐藏量子比特的渐近速率。也就是说,每一方持有与隐藏状态相同大小的份额,以领先的顺序,准确性和安全性参数引起的开销是渐近可忽略的。数据隐藏态具有非常不寻常的纠缠特性,我们简要讨论。

英文摘要:

We present protocols for multiparty data hiding of quantum information that implement all possible threshold access structures. Closely related to secret sharing, data hiding has a more demanding security requirement: that the data remain secure against unrestricted LOCC attacks. In the limit of hiding a large amount of data, our protocols achieve an asymptotic rate of one hidden qubit per local physical qubit. That is, each party holds a share that is the same size as the hidden state to leading order, with accuracy and security parameters incurring an overhead that is asymptotically negligible. The data hiding states have very unusual entanglement properties, which we briefly discuss.
