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. Since October 2016, he has been senior researcher at the
Fraunhofer Institute for Secure Information Technology in Germany,
leading the Post-Quantum Cryptography group at the department
Cyber-Physical Systems and Automotive Security. Since June 2019, he has
been leading the department Advanced Cryptographic Engineering with four
junior researchers and several student research assistants. His main
fields of research are embedded cryptography and PQC.
