Ph.D. Position in Information Theory—Covert Communication


Catégorie : Doctorant


This Ph.D. thesis will be supervised by Dr. Ligong Wang, chargé de recherche with CNRS. The research will be carried out at ETIS laboratory located in Cergy-Pontoise. Currently, the expected starting date is around 1 Oct. 2017.

This Ph.D. thesis is funded by the I-SITE Paris Seine project “Risk, Security, Society”.

 

Description

Covert communication refers to scenarios where the communicating parties try to conceal their communication activity from a potential eavesdropper or warden. Recent works have identified the ultimate performance limit for covert communications in various types of media. In particular, it is known that, for many communication channels, covert communication obeys the "square-root law", meaning that the total amount of information that can be communicated covertly scales like the square-root of total communication time.

The proposed thesis addresses several important open problems in covert communications. They concern continuous-time channels, quantum channels, and code design.
