Elena Andreeva
Assistant Prof. / PhD
About
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, storage and private computation.
Previously, 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.
More details about my research can be found on my personal webpage https://elenandreeva.github.io.
I am always looking for motivated students! Contact me if you are interested in working with me and have a look at our open positions and thesis opportunities!
