摘要:

本文研究了复合多址信道(MAC)上的保密通信问题。在这个信道中,我们假设其中一个传输的消息是机密的,只由其相应的接收器解码,并对其他接收器保密。对于这个建议的设置(复合MAC与机密消息),我们推导出一般的内部和外部界限的保密能力区域。此外,作为例子,我们调查“少噪音”和“高斯”版本的这个通道,并扩展到这些情况下的离散无记忆版本的结果。此外,提供高斯情况下的数值例子,我们说明了复合MAC和复合MAC与机密消息的可实现的速率区域之间的比较。

英文摘要:

In this paper, we study the problem of secret communication over a Compound Multiple Access Channel (MAC). In this channel, we assume that one of the transmitted messages is confidential that is only decoded by its corresponding receiver and kept secret from the other receiver. For this proposed setting (compound MAC with confidential messages), we derive general inner and outer bounds on the secrecy capacity region. Also, as examples, we investigate 'Less noisy' and 'Gaussian' versions of this channel, and extend the results of the discrete memoryless version to these cases. Moreover, providing numerical examples for the Gaussian case, we illustrate the comparison between achievable rate regions of compound MAC and compound MAC with confidential messages.
