The capacity of the Gaussian wiretap channel model is analyzed when there are multiple
antennas at the sender, intended receiver and eavesdropper. The associated channel …

We consider the MIMO wiretap channel, that is a MIMO broadcast channel where the
transmitter sends some confidential information to one user which is a legitimate receiver …

The topic of information theoretic security is introduced and the principal results in this area
are reviewed. The basic wire-tap channel model is considered first, and then several specific …

We consider the problem of secure communication with multiantenna transmission in fading
channels. The transmitter simultaneously transmits an information-bearing signal to the …

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 …

We consider a cooperative wireless network in the presence of one or more eavesdroppers,
and exploit node cooperation for achieving physical (PHY) layer based security. Two …

The secrecy capacity of the multiple-antenna wiretap channel under the average total power
constraint was recently characterized, independently, by Khisti and Wornell and Oggier and …

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 …

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 …

This paper considers the problem of secret communication over a two-receiver multiple-
input multiple-output (MIMO) Gaussian broadcast channel. The transmitter has two …
