Talk Title: Physical Layer Security in future agile networks

Abstract:

The development of secure and agile future networks is highly crucial. The SWAN project aims at shielding current and future communication everyday networks against malicious cyber-attacks, such as sniffing, jamming and denial of service. Specific use cases are being investigated, such as mobile networks, WiFi, GNSS and IoT. This seminar will greatly focus on the IoT systems use case, and in particular LoRa-LoRaWAN. The functionality and architecture of LoRa-WAN will be discussed, along with performance evaluation. Moreover, a brief look at anticipated attacks will be given, along with state-of the-art detect and defence mechanisms from a physical layer perspective.

Speaker Bio:

Vaia has graduated with a Meng in Electronic Engineering from the University of Reading in 2005. Later, she has been awarded a position in the first year of the CDT in Communications in the University of Bristol. Her PhD research focused on interference management in 5G Networks. She was working on Interference Alignment, Topological Interference Management and Non-Orthogonal Multiple Access. She graduated in 2015, and since then she has been part of the CSN and Smart Internet Lab as a Senior Research Associate.

She has worked on EU and UK funded, such as 5GXHaul, 5G-PICTURE and MANTRA, focusing on signal processing algorithms and performance evaluation of 5G networks, mostly for vehicular communications, looking into mmWave and Massive MIMO. She has also performed several field trials, investigating system performance and channel propagation in both fixed and mobile networks. 

Currently, she is working on the SWAN project, which aims to the development of secure and agile future networks. She is focusing on different types of anticipated attacks in different systems, such as 4G/5G, IoT and WiFi. Also, she is investigating novel detect and defence mechanisms in the physical layer against cyber-attacks.
