Security in wireless networks has traditionally been considered to be an issue to be
addressed separately from the physical radio transmission aspects of wireless systems …

We find the secrecy capacity of the 2-2-1 Gaussian MIMO wiretap channel, which consists of
a transmitter and a receiver with two antennas each, and an eavesdropper with a single …

In this paper, we consider the Gaussian multiple-input multiple-output (MIMO) multi-receiver
wiretap channel in which a transmitter wants to have confidential communication with an …

Wireless communication is susceptible to eavesdrop** attacks because of its broadcast
nature. This paper illustrates how interference can be used to counter eavesdrop** and …

We investigate the effects of user cooperation on the secrecy of broadcast channels by
considering a cooperative relay broadcast channel. We show that user cooperation can …

The focus of this paper is an information-theoretic study of retransmission protocols for
reliable packet communication under a secrecy constraint. The h ybrid a utomatic r …

We study the security of communication between a single transmitter and many receivers in
the presence of an eavesdropper for several special classes of broadcast channels. As the …

In this paper, we consider a two-way relay network with two sources and multiple
cooperative relays in the presence of an eavesdropper. To guarantee the secrecy, a null …

Due to the broadcast nature of the wireless medium, wireless communication is susceptible
to adversarial eavesdrop**. This paper describes how eavesdrop** can potentially be …

The problem of secure communication over Multiple-Access Wiretap channel (MAC-WTC)
under strong secrecy criterion is investigated. A new technique based on channel output …
