Topic Overview:
Wireless channels and networks are particularly vulnerable to attacks and threats. This presentation introduces information-theoretical channel models and presents secure coding methods to prevent information leaks while ensuring reliable communication between legitimate parties.

Since its introduction by Shannon, the ubiquitous principles of information theory have been successfully applied to a large variety of scientific domains including communications, error control coding, cryptography, source coding, mathematics, physics, biology, etc. In this presentation, applications of information theory to practical problems of secrecy over wireless channels and networks will be presented. First, the context of secure and robust communications over physical wireless channels will be exposed. This will be followed by an overview of the relevant principles of information theory leading to the definition of information-theoretic measures in wiretap channels. Channel coding methods will be presented as means to protect the confidentiality of information transmitted over channels vulnerable to passive and active threats.
