AI总结:

本文提出了一种基于量子光学的位承诺协议,假设网络提供商能防止窃听,并在诚实但好奇的设定下证明其安全性。

摘要:

随着人工智能和机器学习的兴起,大量私人信息正被涌入应用领域。这种发展引发了隐私问题,因为私人数据集可能被窃取或滥用以非授权目的。安全函数计算旨在通过允许服务提供商在不读取数据本身的情况下计算数据提供者持有的数据集的函数来解决此类问题。此类任务的基础原始素是位承诺(BC),已知在不加入额外假设的情况下无法实现。鉴于该主题的紧迫性,因此开发BC系统并证明其在合理假设下的安全性非常重要。在本文中,我们提供了一种新的量子光学BC协议,该协议假设网络提供商将保护传输线免受窃听。在这一额外假设下,我们证明了我们协议在诚实但好奇的设置中的安全性,并讨论了在我们协议背景下Mayer攻击的难度。

英文摘要:

With the rise of artificial intelligence and machine learning, a new wave of private information is being flushed into applications. This development raises privacy concerns, as private datasets can be stolen or abused for non-authorized purposes. Secure function computation aims to solve such problems by allowing a service provider to compute functions of datasets in the possession of a a data provider without reading the data itself. A foundational primitive for such tasks is Bit Commitment (BC), which is known to be impossible to realize without added assumptions. Given the pressing nature of the topic, it is thus important to develop BC systems and prove their security under reasonable assumptions. In this work, we provide a novel quantum optical BC protocol that uses the added assumption that the network provider will secure transmission lines against eavesdropping. Under this added assumption, we prove security of our protocol in the honest but curious setting and discuss the hardness of Mayer's attack in the context of our protocol.
