Post-Quantum Signatures from Threshold Computation in the Head

April 11, 2024

Presenters

Matthieu Rivain - CryptoExperts

Description

The submitted presentation is about the Threshold Computation in the Head (TCitH) framework that we propose in [FR22] (Asiacrypt 2023) and improve in a recent preprint [FR23b]. This framework extends common MPC-in-the-Head techniques by using threshold secret sharing (and in particular Shamir’s secret sharing) instead of additive sharing. For some MPCitH-based post-quantum signatures, this approach can achieve significant improvements in terms of sizes and timings.
