带反馈的保密通信

Secret Communication with Feedback

Deniz Gunduz, D. Richard Brown, H. Vincent Poor

摘要:

研究了带反馈的保密通信。提出了一种利用反向信道产生共享秘密密钥的可验证性方案。被认为是二进制对称的前向和后向信道的情况下,所提出的方案和毛雷尔的编码方案的组合,以实现提高保密率。高斯信道的情况下,完美的输出反馈进行了分析和Schalkwijk-Kailath编码方案,以实现该信道的保密容量。

英文摘要:

Secure communication with feedback is studied. An achievability scheme in which the backward channel is used to generate a shared secret key is proposed. The scenario of binary symmetric forward and backward channels is considered, and a combination of the proposed scheme and Maurer's coding scheme is shown to achieve improved secrecy rates. The scenario of a Gaussian channel with perfect output feedback is also analyzed and the Schalkwijk-Kailath coding scheme is shown to achieve the secrecy capacity for this channel.
