Biografie

Julian Renner was born in Eggenfelden, Germany. He received the B.Sc. and M.Sc. degree (with high distinction) in electrical engineering from the Technische Universität München (TUM), München, Germany, in 2014 and 2016, respectively. During his Master’s Thesis, he worked on a joint research project of the Institute for Communications Engineering, TUM, and the Coding and Visual Communication Group, Department of Photonics Engineering, Technical University of Denmark (DTU), Denmark. From February 2017 to October 2017, he conducted analytic- and simulation-based research in the field of waveform design for joint automotive radar and V2X communication at the Signal Processing Systems (SPS) Group, Department of Electrical Engineering, Eindhoven University of Technology (TU/e), Netherlands. Since November 2017, he is pursuing the Ph.D. degree at the Coding for Communications and Data Storage (COD) group, TUM.

Protected Code-based Post-Quantum Security

Protected Code-based Post-Quantum Security

Beschreibung

The foreseeable breakthrough of quantum computers represents a risk for communication which uses public-key cryptography. In order to prepare for such an event, embedded devices must integrate post-quantum cryptography, a set of algorithms based on mathematical problems that remains secure even in the presence of the quantum computers. Code-based is one of the most promising post-quantum cryptography. However, the implementation of code-based cryptography has two main challenges: i) satisfy performance and power constraints; and ii) resist side-channel attacks, which uses leakages derived from the implementation (timing, power or electromagnetic characteristics) to retrieve the secret information. The goal of this thesis is to implement a protected version (resistant to side-channel attack) of the newest version of the Gabidulin-Paramonov-Tretjakov code-based post-quantum cryptosystem. This Master thesis will be supervised by Dr. Johanna Sepúlveda (Chair of Security in Information Technology) and Prof. Dr.-Ing. Antonia Wachter-Zeh (Professorship for Coding for Communications and Data Storage).
