On Message Authentication Channel Capacity Over a Wiretap Channel

IEEE Transactions on Information Forensics and Security, 2022
In this paper, a novel message authentication model using the same key over wiretap channel is proposed to achieve information-theoretic security. Specifically, in the proposed model, there is a discrete memoryless channel $W_{1}\!: \!

The Wiretap Channel with a Cache

2018 IEEE International Symposium on Information Theory (ISIT), 2018
We consider the wiretap channel when a (secure) cache memory is added to the legitimate receiver. With the goal of utilizing coded caching for improving secrecy, during the cache placement phase, the receiver caches a function of the files, and the secret key shared with the transmitter subject to the memory constraint. The signals transmitted to serve

Secrecy Performance of the MIMO VLC Wiretap Channel With Randomly Located Eavesdropper

IEEE Transactions on Wireless Communications, 2020
We study in this paper the secrecy performance of the multiple-input multiple-output (MIMO) visible light communication (VLC) wiretap channel. The underlying system model comprises three nodes: one transmitter, equipped with multiple fixtures of LEDs ...

Secure Degrees of Freedom of MIMO Two-Way Wiretap Channel With no CSI Anywhere

IEEE Transactions on Wireless Communications, 2020
This article considers a two-way multiple-input multiple-output (MIMO) Rayleigh block fading wiretap channel with two full-duplex nodes (Alice and Bob) exchanging messages simultaneously and wiretapped by a $ {N}_{ {e}}$ -antennas eavesdropper (Eve ...

Erasure adversarial wiretap channels

2015 53rd Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2015
In an erasure adversarial wiretap channel (eAWTP-channel), the adversary can select a fraction ρr of the codeword to read, and a fraction ρe of the codeword to erase. The model can be seen as an extension of the wiretap II model where the adversary not only selects its view of the transmitted word, but also can erase a fraction of the codeword.

Channel-Correlation-Enabled Transmission Optimization for MISO Wiretap Channels

IEEE Transactions on Wireless Communications, 2021
An artificial noise (AN)-aided beamformer specific to correlated main and wiretap channels is designed in this paper. We consider slow-fading multiple-input-single-output wiretap channels with multiple passive single-antenna eavesdroppers in which an ...

On the Gaussian MIMO Wiretap Channel

2007 IEEE International Symposium on Information Theory, 2007
Wyner's wiretap channel is generalized to the case when the sender, the receiver and the eavesdropper have multiple antennas. We consider two cases: the deterministic case and the fading case. In the deterministic case, the channel matrices of the intended receiver and the eavesdropper are fixed and known to all the nodes.
