ILIA ILIASHENKO (Илья Ильяшенко)
I am a research engineer at Inversed Tech. My research interests lie at the intersection of cryptography and computational number theory focusing on secure computation methods. More precisely, I study homomorphic encryption schemes based on Euclidean lattices, secure multi-party computation methods, interactive proofs and their applications to data privacy and integrity.
