Christian Schaffner

Christian Schaffner is a Researcher at the University of Amsterdam and Centrum Wiskunde & Informatica (CWI) in the Algorithms and Complexity department, focusing on quantum cryptography and post-quantum secure protocols. He leads projects like 'Taming Quantum Adversaries' and holds a Veni Grant from NWO (2010). His work emphasizes cryptographic protocols resilient to quantum computing threats, including zero-knowledge proofs, secure multi-party computation, and verifiable delay functions.

Key research areas include quantum-resistant cryptographic schemes, homomorphic encryption, and protocols in the quantum random oracle model. Notable contributions include advancements in NIZKs, oblivious transfer in noisy-storage models, and quantum secure computation frameworks.

He has authored over 40 publications in top venues like CRYPTO, EUROCRYPT, and Nature Communications. His grants include funding for research on quantum cryptography and homomorphic encryption. Schaffner collaborates with institutions like CWI and presents regularly on quantum computing security at international conferences.
