Info. Theoretic Security

Supported through NSF CCF-1318980 (formerly CCF-1054338)

PI: Lifeng Lai

Recent years have witnessed a resurgence in research interest in information theoretic secrecy. This flurry of work has largely targeted the wireless scenario and, as such, has significantly enhanced our understanding of the fundamental limits and principles governing the design and analysis of secure wireless communication systems. However, most of these recent works consider only the confidentiality issue. The study of more complicated and practical models that involve active attackers and/or dishonest legitimate users has been limited.

The overarching goal of the project is to develop an information theoretic framework for wireless security system design. In this framework, wireless channels’ physical layer resources will be systematically exploited to design secure wireless systems that provide provable confidentiality, integrity and privacy. The project aims to design systems that can deal with general scenarios (more than secrecy in information transmission) while enjoying analytic guarantees provided by the information theoretic approach.
