Dr.-Ing. Thomas Pöppelmann

I am a Senior Staff Engineer Security Architecture and Cryptography Research in the platform concept engineering group of the Chip Card & Security division of Infineon Technologies AG in Munich. My main area of work is the development of concepts for secured cryptographic modules, security standardization, and innovation projects. My research interests are physical protection of cryptographic implementations, embedded security, post-quantum cryptography, and practical lattice-based cryptography. In 2015 I obtained my PhD (Dr.-Ing.) on practical lattice-based cryptography under the supervision of Prof. Dr.-Ing. Tim Güneysu at Ruhr-University Bochum.

  • My main research interests are the efficient and secure implementation of cryptographic algorithms on various target devices. This includes standard algorithms (e.g., AES, RSA, ECC) but especially so called post-quantum cryptography that could resist attacks by future quantum computers. My focus in this area is the efficient implementation of ideal lattice-based cryptography on embedded systems (e.g., FPGA, ARM, and ATMega platforms).
  • Infineon can offer internships or supervision of MSc and BSc theses in the field of secure hardware or cryptography. If you are interested in applying please drop me an email.
