Codes for wireless wiretap channels

2014 IEEE Information Theory Workshop (ITW 2014), 2014
In this presentation we are interested in coding for wiretap wireless channels. First part is devoted to design criteria, second part will deal with the codes themselves. Nested lattices are the main ingredients to be used. We start with the Gaussian wiretap channel where it is shown that theta series have to be minimized.

A statistical physics approach to the wiretap channel

2013 IEEE International Symposium on Information Theory, 2013
The secrecy rate of Wyner wiretap channels is analyzed for general classes of sources, sensing schemes, and channel distributions. Using the replica method, heuristic closed form expressions are obtained for the asymptotic secrecy rate as a function of the statistics of the system model.

Wiretap channel II with a noisy main channel

2015 IEEE International Symposium on Information Theory (ISIT), 2015
In this paper, a wiretap channel where the transmitter and receiver communicate through a discrete memoryless channel, and the eavesdropper (Eve) has perfect access to a fixed fraction of transmitted symbols (of its choosing) is considered. An outer bound for the rate-equivocation region of the channel, for all such fractions, is derived. An achievable

LDPC Codes for the Gaussian Wiretap Channel

IEEE Transactions on Information Forensics and Security, 2009
This paper presents a coding scheme for the Gaussian wiretap channel based on low-density parity-check (LDPC) codes. The messages are transmitted over punctured bits to hide data from eavesdroppers. The proposed coding scheme is asymptotically effective in the sense that it yields a bit-error rate (BER) very close to 0.5 for an eavesdropper whose ...
