Short CV

Michael Pehl received his Dr.-Ing. degree (summa cum laude) 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.  He habilitated in the area of hardware security in 2024 with a thesis entitled "Design, Evaluation, and Application of Security Primitives that are Based on Hardware-Intrinsic Features".
Since 2012 he has been researcher and teaching associate at the Institute for Security in Information Technology and currently holds the position of an academic senior counillor (Akad. ORat). He leads a research group on Hardware-Intrinsic Security and focuses his current research on Physical Unclonable Functions (PUFs). Further research interests include topics like side channel analysis and tools to support secure design. He teaches a number of different courses as stated below. His research interests include PUFs, TRNGs, Side-Channel Analysis and Fault Injection and corresponding countermeasures, and secure design. He is member of the Center of Competence for Design of Electronic Circuits and Systems (DECS) at TUM. From 2014 until 2022 he was also board member of the graduate center of the previous Department of Electrical and Computer Engineering at the Technical University of Munich.

Hardware Acceleration of Fully Homomorphic Encryption

Description

Fully Homomorphic Encryption (FHE) is a promising technology that enables calculations to be performed on encrypted data. It has the potential to significantly alter privacy considerations in cloud computing, but its widespread adoption is hindered by high computational and memory requirements. Significant advancements in algorithmic and mathematical optimizations have greatly improved the performance of FHE schemes. However, computations on encrypted data are still several orders of magnitude slower than equivalent computations on plaintext data when performed purely in software.  Therefore, it is crucial to develop hardware accelerators for FHE to bridge this performance gap and make the usage of FHE more practical.
In recent years, several hardware accelerators for different schemes have been proposed. Most hardware accelerators are tailored for a specific scheme and parameter set. Typically, in order to achieve flexibility, one has to sacrifice performance.
This work shall provide a survey of methodologies and techniques for designing both flexible and high-performance accelerators. It should give an overview of existing hardware accelerators and their underlying architectural features, which enable high performance and flexibility. References [1] and [2] can be used as a starting point for literature research.
