I am a cryptographer and co-founder at TACEO GmbH. Before that I obtained my PhD in Cryptography at Graz University of Technology. My main research interests include privacy enhancing technologies (FHE, MPC, ZKP), domain-specific symmetric primitives, and their application to real-world use cases.

Find more information about myself, my research, talks, and publications on my personal website rwalch.at.

• (Fully) Homomorphic Encryption (FHE)
• Multiparty Computation (MPC)
• Zero-Knowledge Proofs (ZKP)
• Post-Quantum Signatures
• Efficient Implementations
• Ciphers for MPC, FHE, and ZKP

Here is a list of some of my public repositories I coded for my research:

• Hybrid Homomorphic Encryption
• Hash Functions for Zero Knowledge Zoo
• MPC-friendly PRFs Zoo
• Corona Heatmap
• CryptoTL: Encrypted Transfer Learning
• MPC Accumulator
• FPGA Based Picnic Coprocessor
