基于信道状态的认知干扰信道保密性研究

On The Secrecy of the Cognitive Interference Channel with Channel State

Hamid G. Bafghi, Babak Seyfe

摘要:

本文研究了认知状态相关干扰信道中的保密问题。在这种情况下,我们有一个主要的和认知发射机-接收机对。认知发送器将主发送器的消息作为边信息。此外,信道的状态在认知编码器处是已知的。因此,认知编码器使用此边信息与主发送器合作,并机密地发送其单独的消息。推导了该信道的可达速率区域和速率区域的外边界。所得结果作为特例推广到已有的工作中。

英文摘要:

In this paper the secrecy problem in the cognitive statedependent interference channel is considered. In this scenario we have a primary and a cognitive transmitter-receiver pairs. The cognitive transmitter has the message of the primary sender as side information. In addition, the state of the channel is known at the cognitive encoder. So, the cognitive encoder uses this side information to cooperate with the primary transmitter and sends its individual message confidentially. An achievable rate region and an outer bound for the rate region in this channel are derived. The results are extended to the previous works as special cases.
