私有双终端假设检验（CS IT）---用户7305506

我们研究带有简单假设的私有两终端假设测试，其中的隐私目标是确保在告知用户正确的假设时，参与测试协议的用户不会透露有关其他用户观察的其他信息。结果显示，通常，如果用户无法访问相关（但不常见）的随机性，则无法实现有意义的正确性和隐私性。当用户可以访问非平凡的相关随机性（允许安全多方计算的随机性）时，我们将表征最佳正确性和隐私错误指数。

原文标题：Private Two-Terminal Hypothesis Testing

原文：We study private two-terminal hypothesis testing with simple hypotheses where the privacy goal is to ensure that participating in the testing protocol reveals little additional information about the other user's observation when a user is told what the correct hypothesis is. We show that, in general, meaningful correctness and privacy cannot be achieved if the users do not have access to correlated (but, not common) randomness. We characterize the optimal correctness and privacy error exponents when the users have access to non-trivial correlated randomness (those that permit secure multiparty computation).
