Tim Fritzmann

Since 2022, Tim Fritzmann works as a Senior Software Engineer Cryptography at Infineon Technologies AG. During his PhD at the Technical University of Munich, he investigated efficient and secure hardware/software implementations for Post-Quantum Cryptography. In 2017, he obtained the master’s degree in Electrical Engineering at the Technical University of Munich. For his master’s thesis, he received the Walter Gademann award. In 2013, he obtained the bachelor’s degree in Electrical Engineering and worked then for two years as a hardware engineer at Thales in the field of electromagnetic compatibility (EMC).

Research Interests:

  • Post-Quantum Cryptography / Lattice-Based Cryptography
  • Secure and efficient HW/SW implementations
  • Error-Correcting Codes
  • RISC-V Co-Processor Design
