Authentication over Noisy Channels
Lifeng Lai, Hesham El Gamal, H. Vincent Poor
In this work, message authentication over noisy channels is studied. The model developed in this paper is the authentication theory counterpart of Wyner's wiretap channel model. Tw…
Cognitive Interference Channels with Confidential Messages
Yingbin Liang, Anelia Somekh-Baruch, H. Vincent Poor +2
The cognitive interference channel with confidential messages is studied. Similarly to the classical two-user interference channel, the cognitive interference channel consists of t…
Secrecy Capacity of the Wiretap Channel with Noisy Feedback
Lifeng Lai, Hesham El Gamal, H. Vincent Poor
In this work, the role of noisy feedback in enhancing the secrecy capacity of the wiretap channel is investigated. A model is considered in which the feed-forward and feedback sign…
Secrecy Capacity Region of Binary and Gaussian Multiple Access Channels
Yingbin Liang, H. Vincent Poor
A generalized multiple access channel (GMAC) with one confidential message set is studied, where two users (users 1 and 2) attempt to transmit common information to a destination,…
Game-Theoretic Power Control in Impulse Radio UWB Wireless Networks
Giacomo Bacci, Marco Luise, H. Vincent Poor
In this paper, a game-theoretic model for studying power control for wireless data networks in frequency-selective multipath environments is analyzed. The uplink of an impulse-radi…
Secure Communication over Fading Channels
Yingbin Liang, H. Vincent Poor, Shlomo Shamai
The fading broadcast channel with confidential messages (BCC) is investigated, where a source node has common information for two receivers (receivers 1 and 2), and has confidentia…
