Dipl.-Ing. B.Tech.

Secure Systems, PhD Student

Aikata is a full-time Ph.D. student and part-time traveler. She received her Master's degree (with distinction) in Computer Science from TU Graz in 2022 and her master's thesis, titled “Efficient Polynomial Arithmetic Architecture for Saber and Dilithium” received the 1st prize in the TU Graz Forum Technology and Society 2022. She did her bachelor's in technology from the Indian Institute of Technology (IIT) Bhilai in Computer Science. She intends to explore lattice-based cryptography applications and Europe during her Ph.D.
