New Results on Multiple-Input Multiple-Output Broadcast Channels with Confidential Messages [PDF]
, 2011 This paper presents two new results on multiple-input multiple-output (MIMO) Gaussian broadcast channels with confidential messages. First, the problem of the MIMO Gaussian wiretap channel is revisited.

Capacity-equivocation region of a special case of wiretap channel with noiseless feedback
Journal of Communications and Networks, 2015 The general wiretap channel with noiseless feedback is first investigated by Ahlswede and Cai, where lower and upper bounds on the secrecy capacity are provided in their work. The upper bound is met with equality only in some special cases. In this paper, we study a special case of the general wiretap channel with noiseless feedback (called non ...

On Secure Transmission over Parallel Relay Eavesdropper Channel [PDF]
, 2010 We study a four terminal parallel relay-eavesdropper channel which consists of multiple independent relay-eavesdropper channels as subchannels. For the discrete memoryless case, we establish inner and outer bounds on the rate-equivocation region.

Source-Channel Secrecy with Causal Disclosure [PDF]
, 2012 Imperfect secrecy in communication systems is investigated. Instead of using equivocation as a measure of secrecy, the distortion that an eavesdropper incurs in producing an estimate of the source sequence is examined.

Secure Lossy Source Coding with Side Information at the Decoders [PDF]
, 2010 This paper investigates the problem of secure lossy source coding in the presence of an eavesdropper with arbitrary correlated side informations at the legitimate decoder (referred to as Bob) and the eavesdropper (referred to as Eve).

Improved Rate-Equivocation Regions for Secure Cooperative Communication
, 2011 A simple four node network in which cooperation improves the information-theoretic secrecy is studied. The channel consists of two senders, a receiver, and an eavesdropper.

Performance Analysis and Design of Two Edge Type LDPC Codes for the BEC Wiretap Channel
, 2011 We consider transmission over a wiretap channel where both the main channel and the wiretapper's channel are Binary Erasure Channels (BEC). We propose a code construction method using two edge type LDPC codes based on the coset encoding scheme.

The MIMO wiretap channel [PDF]
, 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.

On the Construction of Polar Codes for Achieving the Capacity of Marginal Channels
, 2017 Achieving security against adversaries with unlimited computational power is of great interest in a communication scenario. Since polar codes are capacity achieving codes with low encoding-decoding complexity and they can approach perfect secrecy rates ...
