Large and powerful quantum computers are threatening to break current cryptography like RSA, DH, DSA, ECDH, and EDSA. In response to such quantum computers being expected to emerge in the next decades, the international research community and standardization agencies are working on establishing Post-Quantum Cryptography (PQC) as the next generation of cryptography. The main disadvantage of PQC compared to current cryptography is its generally higher cost in regard to computation, storage, or network throughput. While these demands can be served by modern computing devices like servers, PCs, notebooks, tablets, and smart phones connected by high-speed Internet, the increased resource requirements of PQC pose a significant burden on resource restricted embedded devices. Therefore, targeted research in PQC on embedded devices is required in order to keep such devices secure and operational for the upcoming future. This talk gives a brief overview over the threat of quantum computers on current IT security, an introduction into PQC, and a closer look into recent research on embedded PQC.

Dr. Ruben Niederhagen obtained his PhD from Eindhoven University of Technology in the Netherlands on the topic "Parallel Cryptanalysis" in 2012 and then was postdoctoral researcher at the Institute of Information Science at Academia Sinica in Taiwan and at the Department of Mathematics and Computer Science at Eindhoven University of Technology. In 2016, he joined the Fraunhofer Institute for Secure Information Technology in Germany as senior researcher, leading the Post-Quantum Cryptography group at the department Cyber-Physical Systems and Automotive Security. In 2019, he became head of the department Advanced Cryptographic Engineering with four junior researchers and several student research assistants. Since November 2020, he has been Assistant Professor at the Department of Mathematics and Computer Science (IMADA) at the University of Southern Denmark (SDU). His main fields of research are embedded cryptography and PQC.
