Quantum-Resistance in the Upcoming NIST Call for Threshold Schemes

March 26, 2023


Luís T. A. N. Brandão - NIST/Strativia


Abstract. This lightning talk at the Real World PQC workshop highlights how the upcoming "NIST Call for Multi-Party Threshold Schemes" (see NISTIR-8214C-ipd) has a number of opportunities to explore quantum resistance in the scope of threshold schemes, where secret/private keys are secret-shared across various parties. The scope of primitives of interest goes beyond regular signatures, public-key encryption and block-ciphers, and considers also schemes with advanced features (such as homomorphic, or identity-based), zero-knowledge proofs and various gadgets useful for secure multi-party computation. Public feedback about the initial public draft is open until 2023-April-10.
