双向有线分接信道的可兑换费率

Achievable Rates for Two-Way Wire-Tap Channels

Ender Tekin, Aylin Yener

摘要:

我们考虑双向窃听信道,其中两个用户在存在窃听者的情况下相互通信,窃听者可以通过多路访问信道访问通信。我们发现可实现的速率为两种不同的情况下,高斯双向窃听信道,(GTW-WT),和二进制添加剂双向窃听信道,(BATW-WT)。它示出的双向通道固有地提供了一个独特的优势,有线窃听的情况下,用户知道自己的传输信号,并在效果上帮助加密其他用户的消息,类似于一个一次性垫。我们比较的高斯多址窃听信道(GMAC-WT)的可实现的速率来说明这一优势。

英文摘要:

We consider two-way wire-tap channels, where two users are communicating with each other in the presence of an eavesdropper, who has access to the communications through a multiple-access channel. We find achievable rates for two different scenarios, the Gaussian two-way wire-tap channel, (GTW-WT), and the binary additive two-way wire-tap channel, (BATW-WT). It is shown that the two-way channels inherently provide a unique advantage for wire-tapped scenarios, as the users know their own transmitted signals and in effect help encrypt the other user's messages, similar to a one-time pad. We compare the achievable rates to that of the Gaussian multiple-access wire-tap channel (GMAC-WT) to illustrate this advantage.
