Vasilios Mavroudis is a doctoral researcher in the Information Security Group at University College London. He studies security and privacy aspects of digital ecosystems, with a focus on emerging technologies and previously unknown attack vectors. He is currently working on a high-assurance cryptographic hardware. In cooperation with industrial partners, he has recently prototyped a high-assurance hardware architecture, that maintains its security properties even in the presence of malicious hardware components. Past works include his recent publication on the ultrasound tracking ecosystem which received wide-spread attention and is considered the seminal work on that ecosystem, and auditing tools for the Public Key Infrastructure of Deutsche Bank. Moreover, he has participated in an international consortium studying large-scale security threats in telecommunication networks, and cooperated with UC Santa Barbara in several projects, including a detection system for evasive web-malware. Vasilios holds an Information Security MSc from UCL, and a BSc on Computer Science from University of Macedonia, Greece.
