ZKSC 2026 Workshop

ZKSC 2026 – the Workshop on Zero-Knowledge, Succinct Proofs and Symmetric Cryptography – successfully took place on February 9–11, 2026. Organized by Elena Andreeva and Georg Fuchsbauer, the event brought together researchers from zero-knowledge and symmetric cryptography, two communities whose interaction is becoming increasingly essential for modern privacy-preserving systems. The workshop formed part of the activities of the Cybersecurity Center TU Wien and the FWF-funded SPyCoDe project, with additional support provided by the Ethereum Foundation.

  • Ivan Visconti: A Few Stops in the Zero-Knowledge Journey,
  • Léo Perrin: When POlynomial System SOlving became a threat for symmetric primitives,
  • Ziyi Guan: On the Security of Succinct Arguments from Probabilistic Proofs,
  • Arnab Roy: When Polynomials Iterate: Structure and Security in Symmetric Cryptography,
  • Abhishek Jain: IVC without Random Oracles,
  • Dmitry Khovratovich: Succinct Proofs in the Core Ethereum Protocol,
  • Stefano Trevisani: New Modes on the Block: Security and Efficiency of Novel AO Compression Modes,
  • Lorenzo Grassi: Greek and Roman Gods in Symmetric-Key Crypto,
  • Justin Thaler (remote talk): Lessons from Jolt: When Do We Need SNARK-Friendly Primitives?,
  • Dmitry Khovratovich: Panel on Poseidon,
  • Michele Orrù (remote talk): A Fiat–Shamir Transformation From Duplex Sponges,
  • Markus Schofnegger: Implementation Characteristics of Hash Functions in Modern Proof Systems,
  • Ngoc Khanh Nguyen: Recent Progress on Lattice-based Zero-Knowledge Proofs,
