Lattice-Based Zero-Knowledge Proofs Ref. 2026_013 About the position The cryptography group at IBM Research in Zurich is looking to hire a Ph.D. student to work on constructions and applications of lattice-based zero knowledge proofs. The group is one of the world-leaders in quantum-safe cryptography research and has significantly contributed to all three lattice-based NIST quantum-safe standards. Our current research emphasis is on practical zero-knowledge proofs based on the same foundations and their application to privacy-preserving cryptography. A motivated researcher should find this to be a very exciting environment to work in. A strong background in (applied) mathematics and some experience with cryptography is desirable. Additionally, the ideal candidate is someone who has a strong interest in high-performance implementations on modern CPU and/or GPU architectures. Zurich is consistently ranked as one of the top cities for living standards and the immediate proximity of lakes and mountains to the lab allows for the pursuit of numerous hobbies.
