隐藏输入函数的安全计算

Secure Computation to Hide Functions of Inputs

Gowtham R. Kurri, Vinod M. Prabhakaran

摘要:

我们考虑一个两用户安全计算问题,其中Alice和Bob交互通信,以计算一些确定性的输入函数。隐私要求是,每个用户不应该学习任何额外的信息,除了可以从自己的输入和输出推断出的输入功能。对于无分布设置,即,当协议对于任意联合输入分布必须是正确的和私有的时,我们完全刻画了所有安全可计算函数的集合。当隐私只需要对鲍勃谁计算一个功能的基础上从爱丽丝的一个单一的传输,我们表明,渐近安全的可计算性是完全安全的可计算性。另外,我们认为窃听者谁可以访问所有的通信,不应该学习任何信息的一些功能的输入(可能不同的功能由用户计算),并表明,互动可能是必要的安全计算。

英文摘要:

We consider a two-user secure computation problem in which Alice and Bob communicate interactively in order to compute some deterministic functions of the inputs. The privacy requirement is that each user should not learn any additional information about a function of the inputs other than what can be inferred from its own input and output. For the distribution-free setting, i.e., when the protocol must be correct and private for any joint input distribution, we completely characterize the set of all securely computable functions. When privacy is required only against Bob who computes a function based on a single transmission from Alice, we show that asymptotically secure computability is equivalent to perfectly secure computability. Separately, we consider an eavesdropper who has access to all the communication and should not learn any information about some function of the inputs (possibly different from the functions to be computed by the users) and show that interaction may be necessary for secure computation.
