Lecturer

About Me

Mohammed El-hajj received my B.S. from the school of computer science in IUL University Lebanon, in 2004, the M.S. from Kingston University, London, in 2008, and the Ph.D. degree in Network Security from University Saint-Joseph, Lebanon, in 2020.

I worked as an assistant professor at the University of Sciences and Arts in Lebanon in the Department of Computer Science department.

Recently, I  have taken a new position as a lecturer at University of Twente.

My research interests span both IoT security and Network Security. They focuses on improving the understanding, design, and performance of authentication protocols for IoT ecosystems, as well as designing a hardware security platform based on Physical Un-clonable Functions (PUF), prone to Machine learning attacks to provide authentication to IoT devices. Digital twins and its usage to enhance security of IoT usecases.

Experienced Assistant Professor with a demonstrated history of working in the higher education industry. Skilled in Software Development, Internet of Things, Network Security, Teaching, and Programming. Strong education professional graduated from the Saint Joseph University of Beirut.

Research

My research interests span both IoT security and Network Security. Much of his work has been on improving the understanding, design, and performance of authentication protocols for IoT ecosystems, mainly by benefiting from different types of Distributed Ledger Technologies (Ethereum Blockchain, IOTA, etc.). Besides understanding and designing a hardware security platform based on Physical Unclonable Functions(PUF) that is prone to Machine learning attacks to provide authentication to IoT devices.

Digital twins and how it can be used to enhance the security of CIs.
