FRAUNHOFER WORKSHOP SERIES (FWS) are bridging academia and industrial experts to tackle foresighted research into practical solutions. Our FWS events include background lectures, round-tables and hands-on sessions. The goal is to contribute to application-oriented research and to support the transfer of academic research to the industrial domain.

Quantum mechanics has been one of the most important achievements in the field of theoretical physics in the 20th century. In the 21st century, we expect as practical application of this theory, the development of quantum computers. Quantum computers will be able to break important cryptographic primitives used in today’s digital communication. Therefore, there are ongoing activities aiming at the development, standardization, and application of post-quantum cryptography, i.e., cryptography that is able to resist attacks by quantum computers.

In this workshop, we will investigate post-quantum primitives targeting the requirements of modern internet applications and resource-restricted embedded hardware architectures used in, e.g., Automotive, Smart Transportation and “Industrie 4.0”. 

  • On the way to Quantum Computing. What is quantum computing and why does it break cryptographic primitives?
  • Challenges for industry and academia
  • Theoretical Background on Post-Quantum Schemes (Code-based, Lattice-based, Hash-based, Multivariate, Supersingular Isogeny)
  • Efficient Implementations of PQ for Hardware and Software: 
  • Optimization in area, memory, speed and power
  • Secure Design of PQ schemes: How to design quantum resistant primitives in practice 
  • Cryptanalysis vs. physical attacks: Side-channel and fault analysis. on PQ crypto systems

Prof. Dr. GU Mile

School of Physical and Mathematical Sciences (SPMS)
Nanyang Technological University (NTU), Singapore

Prof. Dr. Mile Gu is a New Zealand physicist specialising in discovery of new applications for quantum information science. Mile Gu obtained his PhD from the University of Queensland in 2009 in quantum computation. He subsequently joined Institute for Interdisciplinary Information Sciences at Tsinghua University under the China One Thousand Talents Program. Gu has made a number of notable contributions to quantum information science.  These include design of new quantum methods to simulate highly complex systems with drastically reduced resource requirements, the discovery of noise-resilient quantum resources that survive in every day environments, and the design of a new model of quantum computation now employed to build ultra-large entangled states of light.

In 2016, Gu returned in Singapore as a National Research Foundation Fellow, and works jointly at the Complexity Institute and the School of Physical and Mathematical Sciences at Nanyang Technological University. He currently heads the quantum and complexity sciences initiative (QuCSI) - which seeks to uncover new means of harnessing quantum information to better model and simulate complex systems that pervade science and society (

Dr. Bernhard Jungk

Fraunhofer Singapore, Research Fellow
Group "Cyber- and Information Security"

Dr. Bernhard Jungk is Research Fellow at Fraunhofer Singapore’s group for Cyber and Information Security with a focus on industrial cryptography and its application. His fields of activity includes research and development of efficient cryptographic building blocks from basic cryptographic algorithms, such as quantum-safe algorithms to more complex cryptographic protocols. In particular bridging new research to its integration into industrial applications and smart embedded services, related e.g. to the requirements in the automotive sector or industrie 4.0. Previously, he was a postdoctoral researcher at TL@NTU, where he developed efficient implementations of cryptographic algorithms, as well as new side-channel attacks and countermeasures. He obtained his Ph.D at the Goethe University Frankfurt in Germany in 2016. Bernhard gained deep professional experience as an industrial security consultant for several OEMs, Tier-1 and Tier-2 companies in Germany’s Automotive industry sector between 2012 and 2016, mainly in the area of vehicular ad-hoc communication security. In this role, he was actively contributing to the standardisation efforts by ETSI and the C2C Communication Consortium. In particular, he was one of the main contributors for the core security protocol standard for V2X communication by ETSI between 2013 and 2016.
