The Secrecy Capacity of the 2× 2 MIMO Wiretap Channel
نویسندگان
چکیده
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, while the other user is an eavesdropper. Perfect secrecy is achieved when the the transmitter and the legitimate receiver can communicate at some positive rate, while insuring that the eavesdropper gets zero bits of information. In this paper, we compute the secrecy capacity of a two antenna MIMO broadcast channel.

MIMO Wiretap Channels with Arbitrarily Varying Eavesdropper Channel States
In this work, a class of information theoretic secrecy problems is addressed where the eavesdropper channel states are completely unknown to the legitimate parties. In particular, MIMO wiretap channel models are considered where the channel of the eavesdropper is arbitrarily varying over time. Assuming that the number of antennas of the eavesdropper is limited, the secrecy rate of the MIMO wire...
متن کاملCompound Wiretap Channels
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. No matter which states occur, the transmitter guarantees that the receiver decodes its message and that the eavesdropper is kept in full ignorance about the message. The compound wiretap channel...

This paper considers a multiple-input multiple-output (MIMO) Gaussian wiretap channel model, where there exists a transmitter, a legitimate receiver and an eavesdropper, each equipped with multiple antennas. Perfect secrecy is achieved when the transmitter and the legitimate receiver can communicate at some positive rate, while ensuring that the eavesdropper gets zero bits of information. In th...
متن کاملAlmost universal codes for MIMO wiretap channels
Despite several works on secrecy coding for fading and MIMO wiretap channels from an error probability perspective, the construction of information theoretically secure codes over such channels remains as an open problem. In this paper, we consider a fading wiretap channel model where the transmitter has only partial statistical channel state information. We extend the flatness factor criterion...
متن کاملOn the Secrecy Capacity of a MIMO Gaussian Wiretap Channel with a Cooperative Jammer
We study the secrecy capacity of a helper-assisted Gaussian wiretap channel with a source, a legitimate receiver, an eavesdropper and an external helper, where each terminal is equipped with multiple antennas. Determining the secrecy capacity in this scenario generally requires solving a nonconvex secrecy rate maximization (SRM) problem. To deal with this issue, we first reformulate the origina...
