Teklay Gebremichael

Doktorand|Doctoral Student


Teklay Gebremichael has a bachelor degree in information technology from Mekelle Institute of Technology, Ethiopia and studied his Master's Degree at the University of Trento, Italy, in computer science with a specialization in Internet Technologies and security. After graduation, he worked at the same university for two, during which he focused on mobile applications security. Today, Teklay is a PhD-student at STC and he is currently working in the research project SMART.

Area of interest

His current research area is security of Internet of Things (IoT). Specifically, he focuses on developing cryptographic (group) key establishment schemes in the context of IoT. The research challenge consists in designing efficient key establishment algorithms (with regard to computational complexity, memory footprint and power consumption) that are convenient for low computation-power and small storage capacity IoT devices.
