Matthias Minihold

PhD student in Cryptology at Ruhr-Universität Bochum (RUB.de)

Currently, I am a PhD candidate in cryptology at Ruhr-Universität Bochum (RUB).

My main research subjects are Fully Homomorphic Encryption, Lattice-based Cryptology, Deep Neural Networks, and more general Cloud Computing.
I graduated from TU Wien in mathematics, then in November 2015 became a Marie Skłodowska-Curie Research Fellow as part of the ECRYPT-NET project.

Research Interests

  • Fully Homomorphic Encryption (FHE)
    [🔑] Studying FHE schemes, primitives they build upon & their applications
    [🔑] Defining minimal requirements for practical FHE usage, e.g., in Cloud-Computation
    [🔑] Studying functionality limits and practicality of FHE based solutions for various use-cases
  • The Subset-Sum Problems (SSP), Learning With Errors (LWE)
    [🔑] Probabilistic methods to solve hardest instances
    [🔑] Investigating algorithmic lower-bounds from a complexity theoretic perspective
    [🔑] How many items optimally fill my knapsack?
  • Easy to use online privacy tools in digital everyday life
    [🔑] Deploying best practices in times of ubiquitous tracking and profiling
    [🔑] Real-world solutions for artificial intelligence classification on encrypted images & data
    [🔑] Discussing the impact of crypto-technology on the (unheeding?) society
