摘要:

我们认为在一个复合通道的状态时,需要被掩盖的通道进行通信的基本限制。我们的模型与被称为隐蔽通信的研究领域密切相关,隐蔽通信是发射机希望与合法接收机通信的设置,同时确保通信不被对手检测到。在我们的两个状态的掩蔽设置的主要贡献是建立的边界上的吞吐量的关键区域的约束,量化多少状态被掩蔽被定义为两个通道引起的分布之间的总变化距离。对于密钥长度为无限的情况,我们提供了充分的条件,当边界重合的吞吐量,它遵循平方根定律。数值例子,包括高斯信道,来说明我们的结果。

英文摘要:

We consider fundamental limits for communicating over a compound channel when the state of the channel needs to be masked. Our model is closely related to an area of study known as covert communication that is a setting in which the transmitter wishes to communicate to legitimate receiver(s) while ensuring that the communication is not detected by an adversary. The main contribution in our two-state masking setup is the establishment of bounds on the throughput-key region when the constraint that quantifies how much the states are masked is defined to be the total variation distance between the two channel-induced distributions. For the scenario in which the key length is infinite, we provide sufficient conditions for when the bounds to coincide for the throughput, which follows the square-root law. Numerical examples, including that of a Gaussian channel, are provided to illustrate our results.
