Welcome to my webpage! :sparkles:

I am a tenure-track Assistant Professor in the Security and Privacy Research Unit at TU Wien, Vienna, Austria.


I was an Assistant Professor in the Cyber Security Group at DTU, Denmark and a Lecturer in the Cyber Security Research Group at University of Klagenfurt, Austria. Prior to that, I worked as a Research Expert in the COSIC Research Group, KU Leuven, Belgium. My PhD and my Postdoctoral research was also at COSIC and was funded by a PhD and Postdoctoral grants from the Flemish Research Foundation (FWO). I completed my PhD, entitled Domain Extenders for Cryptographic Hash Functions, in 2010 under the supervision of prof. Bart Preneel. I hold a Master’s degree in Computer Science from the University of Saarland, Germany.

Research Interests

My research interests lie in the area of theory and applications of cryptography and more concretely in symmetric cryptography, authenticated encryption, forkciphers, hash functions, key derivation, provable security, privacy-friendly security protocols, and cryptography for blockchains. I am interested in theory and development of provably secure cryptographic designs for secure data communications :satellite:, storage :computer: and private computation :closed_lock_with_key: :cloud:.

Cryptographic designs

Some of my cryptographic design contributions include:

  • ABR tree hashing :deciduous_tree:- novel optimally effeicient tree hash function providing collision security.
  • Forkcipher :fork_and_knife: - a novel expanding symmetric primitive. Our forkcipher instance ForkSkinny is used in the ForkAE authenticated encryption family which is a Round 2 NIST lightweight cryptography qualifer ForkAE.
  • COLM is the development of the original AES-COPA :wine_glass: authenticated encryption scheme which is a winner in the defence-in-depth category of the CAESAR authenticated encryption cryptographic competition. The COLM design was invited for publication in the Journal of Cryptology.
  • PRIMATEs :monkey: PRIMATE lightweight authenticated encryption family (APE, Hanuman, Gibbon) is a Round 2 qualifer in the CAESAR authenticated encryption cryptographic competition.
