Optimizing honest majority threshold cryptosystems

November 4, 2020


Ivan Damgård - Aarhus University


Abstract: We review some ideas that allows optimizing threshold implementations of well-known cryptographic primitives with honest majority and security against malicious adversaries. Specifically, full-fledged zero-knowledge proofs of correct behavior are often not necessary and can be replaced by weaker primitives.

Presented at

NIST Workshop on Multi-Party Threshold Schemes (MPTS) 2020.

Based on a paper with Kasper Dupont.
