Some New Results on the Wiretap Channel with Side Information
In this paper, the model of wiretap channel has been reconsidered for the case that the main channel is controlled by channel state information (side information), and it is available at the transmitter in a noncausal manner (termed here noncausal side information) or causal manner (termed here causal side information). Inner and outer bounds are derived on the capacity-equivocation regions for...
متن کاملWiretap Channel With Side Information
The wiretap channel put forward by Wyner for many years. In this paper, we consider the situation that the wiretapper can not only view the channel output via a second noisy channel, but also can get some side information about the codeword that transmitted in the main noisy channel. The designer tries to build the encoder-decoder in such a way as to maximize the transmission rate R, and the eq...
متن کاملOn The Achievable Rate Region of a New Wiretap Channel With Side Information
A new applicable wiretap channel with separated side information is considered here which consist of a sender, a legitimate receiver and a wiretapper. In the considered scenario, the links from the transmitter to the legitimate receiver and the eavesdropper experience different conditions or channel states. So, the legitimate receiver and the wiretapper listen to the transmitted signal through ...
متن کاملWiretap Channel with Information Embedding on Actions
Information embedding on actions is a new channel model in which a specific decoder is used to observe the actions taken by the encoder and retrieve part of the message intended for the receiver. We revisit this model and consider a different scenario where a secrecy constraint is imposed. By adding a wiretapper in the model, we aim to send the confidential message to the receiver and keep it s...
