EURASIP Journal on Wireless Communications and Networking, 2009 This paper considers the compound wiretap channel, which generalizes Wyner's wiretap model to allow the channels to the (legitimate) receiver and to the eavesdropper to take a number of possible states.

The MIMO wiretap channel [PDF]
2008 3rd International Symposium on Communications, Control and Signal Processing, 2008 We study the MIMO wiretap channel, a MIMO broadcast channel where the transmitter sends some confidential information to one user which is a legitimate receiver, while the other user is an eavesdropper.

Secrecy Results for Compound Wiretap Channels [PDF]
Problems of Information Transmission, 2012 We derive a lower bound on the secrecy capacity of the compound wiretap channel with channel state information at the transmitter which matches the general upper bound on the secrecy capacity of general compound wiretap channels given by Liang et al. and

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 ...

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.

Finite-Blocklength Bounds for Wiretap Channels [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 This paper investigates the maximal secrecy rate over a wiretap channel subject to reliability and secrecy constraints at a given blocklength. New achievability and converse bounds are derived, which are shown to be tighter than existing bounds.

The Computational Wiretap Channel [PDF]
2018 56th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2018 We present the computational wiretap channel: Alice has some data x and wants to share some computation h(x) with Bob. To do this, she sends f(x), where f is some sufficient statistic for h.

Wiretap Channel with Action-Dependent Channel State Information [PDF]
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 Multiple-AccessWiretap Channel [PDF]
Entropy, 2014 In this paper, some new results on the multiple-access wiretap channel (MAC-WT) are provided. Specifically, first, we investigate the degraded MAC-WT, where two users transmit their corresponding confidential messages (no common message) to a legitimate ...
