Virtual Seminar by Prof. Vincent Poor

Dear Colleagues,

The IEEE TCCN Security Special Interest Group is launching a monthly virtual seminar series hosting speakers to highlight the challenges in securing the next generation (xG) wireless networks. The theme of the talks will feature cutting edge research directions addressing both technical and policy issues to advance the state-of-the-art in security techniques, architectures, and algorithms for wireless communications.

The first talk of the series will be delivered by Prof. Vincent Poor, Princeton University.

Date and Time: November 17 at 9AM ET

Registration: Please register using the following link. You will receive a link in your email to attend the talk online.

Title: Physical Layer Security in Wireless Networks

Abstract: The increasing deployment of wireless systems poses security challenges in emerging dynamic and decentralized networks consisting of very large numbers of low-cost and low-complexity devices. Over the last two decades alternative/complementary means to secure data exchange in wireless settings have been investigated in the framework of physical layer security (PLS), addressing jointly the issues of reliability and secrecy. PLS takes advantage of the inherent randomness of wireless communication channels and/or the unclonability of hardware fabrication processes, to harvest entropy and deliver authentication, confidentiality, message integrity, and privacy in demanding scenarios. In this talk, we review these issues from an information theoretic security perspective. PLS relies on information theoretic proofs of (weak or strong) perfect secrecy, a notion first introduced by Shannon in 1949. As such, PLS systems cannot be “broken” irrespective of the adversarial computational power, i.e., the proofs do not rely on any assumptions regarding the hardness of particular families of algebraic problems. There are some fundamental differences between information theoretic security and classical cryptography, and we will also discuss some of the pros and cons of each.
