About me

I am a PhD student since 01.01.2020. at Cryptography and Network Security (CNS) group at TU Darmstadt, Germany. My advisor is Dr. Jean Paul Degabriele.

My main research areas are: tweakable ciphers, authenticated encryption, secure channels, analyzing secure network protocols.

I obtained a BSc in Computer Science at Faculty of Sciences, University of Novi Sad, Serbia. After that I got my MSc in IT Security at Ruhr-University Bochum, Germany.

I contribute to the development of libreswan, an IPsec/IKEv2 open-source client.
