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.
