论文摘要
本文研究了离散无内存（DM）多重访问窃听（MAC-WT）通道的容量区域，除了机密消息，用户还开放消息要传输。所有这些消息均针对合法的接收器，但仅需要保护机密消息免受窃听器的保护。通过使用随机编码，我们发现一个可实现的保密率区域，可以在该区域中实现完美的保密区，即，所有用户都可以与合法的接收器进行通信，而错误的错误可能性很小，而泄漏到窃听者的机密信息往往为零。
This paper investigates the capacity region of a discrete memoryless (DM) multiple access wiretap (MAC-WT) channel where, besides confidential messages, the users have also open messages to transmit. All these messages are intended for the legitimate receiver but only the confidential messages need to be protected from the eavesdropper. By using random coding, we find an achievable secrecy rate region, within which perfect secrecy can be realized, i.e., all users can communicate with the legitimate receiver with arbitrarily small probability of error, while the confidential information leaked to the eavesdropper tends to zero.
