Veronika Kuchta obtained her Diploma degree (equiv. to Master degree) in Mathematics from Karls‐Ruprecht University of Heidelberg (Germany) and her PhD degree in applied cryptography form University of Surrey (United Kingdom) under the supervision of Dr. Mark Manulis. The focus of her PhD thesis was on distributed cryptographic protocols. From December 2015 to March 2018 she was a postdoctoral researcher with the Université libre de Bruxelles (ULB, Belgium). In this time she was a member of the QualSec (quality and security of information systems) group under the supervision of professor Olivier Markowitch and she was working on a project called SeCloud, focusing on security‐driven engineering of cloud‐based applications. Since March 2018 she has been Research Fellow at Monash University, Melbourne, Australia under the supervision of Dr. Joseph K. Liu. Her research interests lie in the areas of post‐quantum cryptography, zero‐knowledge proofs, blockchain. She designed several lattice‐based cryptographic protocols which were pubished and presented at the international conferences. Furthermore, she is interested in different aspects of code‐based cryptography and their relation to lattice‐based cryptoschemes and application to the research area of blockchain.
