Short CV

Michael Pehl received his Dr.-Ing. degree in 2012 from the Technische Universität München. His thesis with title "Discrete Sizing of Analog Integrated Circuits" was carried out at the Institute for Electronic Design Automation and focused on the development of optimization algorithms for yield-aware analog sizing considering discrete design parameters. For this work he received the Kurt-Fischer Prize in 2013.
Since 2012 he is researcher and teaching associate at the Institute for Security in Information Technology. The focus of his current research is on the field of Physical Unclonable Functions (PUFs). Further research interests include topics like side channel analysis and tools to support secure design. He is teaching different courses as stated below.


Topics for Theses and Internships

Bachelor's Theses

Side - channel analysis of error - correcting codes for PUFs

Description

Physical Unclonable Functions (PUFs) exploit manufacturing process variations to generate unique signatures. PUF and error-correcting codes can be joined together to reliably generate cryptographically strong keys. However, the implementation of error-correcting codes is prone to physical attacks like side-channel attacks. Side-channel attacks exploit the information leaked during the computation of secret intermediate states to recover the secret key. Therefore, the implementation of error-correcting codes must also involve the implementation of proper countermeasures against side-channel attacks.

The goal of this thesis is to evaluate the side-channel resistance of a secure implementation of error-correcting codes for PUFs on FPGA. The thesis consists of the following steps:

  • Get familiar with currently available implementations of error-correcting codes for PUFs
  • Adapt and improve current implementations (VHDL)
  • Develop a measurement setup for side-channel analysis (Matlab/Python)
  • Perform side-channel analysis using the state-of-the-art EMF measurement equipment in our lab (Oscilloscope knowledge + Matlab/Python required)

Prerequisites

 The ideal candidate should have:

  • Previous experience in field of digital design (VHDL/Vivado/Xilinx FPGA)
  • Basic knowledge on using lab equipment (e.g Oscilloscope,...)
  • Basic knowledge in statistics
  • Good programming skills in Matlab/Python
  • Attendance at the lecture “Secure Implementation of Cryptographic Algorithms” is advantageous

Side-Channel Enabled Machine Learning of PUFs

Description

Physical Unclonable Functions are security primitves used for key-storage and authentication. Like every security related hardware, they are subject to attacks. For authentication protocolls with PUFs, machine learning is the main threat. However, in several publications, it is combined with side-channel observations in order to enhance performances (e.g., [1])

In this seminar, you will research state of the art regarding this attack vector on PUFs. You will provide an overview over presented attacks and discuss impact and relevance of these attacks.

The seminar (presentation and report) can be provided in German or English languag.

Advances in the Resistance of Physical Unclonable Functions against Machine Learning

Description

Physical Unclonable Functions (PUFs) are security primitives, which derive a secret from tiny, device unique manufacturing variations. Since several years there is an attempt to design a PUF with challenge-response behavior, which allows for leightweight authentication. But until today, every PUF which was presented in this area has been machine learned; i.e., it is possible to derive a sufficiently accurate mathematical clone, so that secure authentication is not possible anylonger. Nevertheless, several attempts have been made to improve the situation; resent approaches are described in [1, 2].

The goal of this seminar is to illustrate the advances in machine-learning resistance of PUFs until today and to highlight different approaches taken to achieve higher resistance, and to compare benefits and drawbacks of the taken approaches.
