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 oneof the world-leaders in quantum-safe cryptography research and has significantlycontributed to all three lattice-based NIST quantum-safe standards. Our currentresearch emphasis is on practical zero-knowledge proofs based on the same foundations and their application to privacy-based cryptography, where the results look very promising. A motivated researcher should find this to be a very exciting and fast-moving environment to work in. The ideal candidate is someone who has strong industrial developmentexperience (preferably, but not necessarily, working on some aspect of zero-knowledge proofs or lattice cryptography) and would like to get into the researchfield by gaining an in-depth understanding of lattice-based cryptography andapply it to designing and deploying practical privacy-based protocols. Strongmathematical foundations and some experience with cryptography is desirable. Zurich is consistently ranked as one of the top cities for living standardsand the immediate proximity of lakes and mountains to the lab allows for thepursuit of numerous hobbies.
