We consider secure multi-terminal source coding problems in the presence of a public helper. Two main scenarios are studied: 1) source coding with a helper where the coded side information from the helper is eavesdropped by an external eavesdropper, 2) triangular source coding with a helper where the helper is considered as a public terminal. We are interested in how the helper can support the source transmission subject to a constraint on the amount of information leaked due to its public nature. We characterize the tradeoff between transmission rate, incurred distortion, and information leakage rate at the helper/eavesdropper in the form of a rate-distortion-leakage region for various classes of problems.

使用公共帮助程序进行安全源编码。

我们在公共帮助者的陪伴下考虑安全的多终端源代码编码问题。研究了两种主要方案：1）使用辅助程序进行源代码编码，其中通过外部窃听者窃听来自该辅助程序的已编码辅助信息； 2）使用辅助程序进行三角源代码编码，其中该辅助程序被视为公共终端。我们感兴趣的是，在由于公共性质而导致的信息泄漏量受到限制的情况下，帮助者如何支持源传输。我们以速率-失真-泄漏区域的形式，针对各种类型的问题，描述了传输速率，引起的失真和辅助/窃听者的信息泄漏速率之间的折衷。
