Wiretap Channel With Side Information

Wiretap 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...

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...

Wiretap 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...

Information hiding: an application of wiretap channels with side information

Wiretap Channel with Action-Dependent Channel State Information

In this paper, we investigate the model of wiretap channel with action-dependent channel state information. Given the message to be communicated, the transmitter chooses an action sequence that affects the formation of the channel states, and then generates the channel input sequence based on the state sequence and the message. The main channel and the wiretap channel are two discrete memoryles...
