Some New Results on the GaussianWiretap Feedback Channel
Entropy, 2019 In this paper, the Gaussian wiretap feedback channel is revisited, and some new resultson its secrecy capacity are obtained. To be specific, first, we show that the Schalkwijk−Kailath (SK)feedback scheme, which achieves the secrecy capacity of the ...

Enhancing secrecy rates in a wiretap channel
Digital Communications and Networks, 2020 Reliable communication imposes an upper limit on the achievable rate, namely the Shannon capacity. Wyner's wiretap coding ensures a security constraint and reliability, but results in a decrease of achievable rate.

Sensing-Assisted Secure Communications over Correlated Rayleigh Fading Channels [PDF]
EntropyWe consider a secure integrated sensing and communication (ISAC) scenario, where a signal is transmitted through a state-dependent wiretap channel with one legitimate receiver with which the transmitter communicates and one honest-but-curious target that

Improved polar-code-based efficient post-processing algorithm for quantum key distribution [PDF]
Scientific Reports, 2022 Combined with one-time pad encryption scheme, quantum key distribution guarantees the unconditional security of communication in theory. However, error correction and privacy amplification in the post-processing phase of quantum key distribution result ...

Secrecy Capacity of the Extended Wiretap Channel II with Noise
Entropy, 2016 The secrecy capacity of an extended communication model of wiretap channelII is determined. In this channel model, the source message is encoded into a digital sequence of length N and transmitted to the legitimate receiver through a discrete memoryless ...

Randomized Convolutional Codes for the Wiretap Channel [PDF]
IEEE Transactions on Communications, 2017 We study application of convolutional codes to the randomized encoding scheme introduced by Wyner as a way of confusing the eavesdropper over a wiretap channel. We describe optimal and practical sub-optimal decoders for the main and the eavesdropper’s channels, and estimate the security gap, which is used as the main metric.

Wiretap Channel with Action-Dependent Channel State Information
Entropy, 2013 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 ...

Some New Results on the Wiretap Channel with Side Information
Entropy, 2012 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 ...
