[ELEN] 2026-01-27 (14:00) : The MPC-in-the-Head Paradigm for Post-Quantum Signatures: Recent Frameworks and Applications

At Shannon

Speaker: Thibauld Feneuil (CryptoExperts)
Abstract: Signature schemes based on the MPC-in-the-Head (MPCitH) paradigm play a central role in post-quantum cryptography, enabling constructions from a broad range of hardness assumptions. In NIST's ongoing process for additional post-quantum digital signature standards, six candidate schemes rely on MPCitH, spanning assumptions from symmetric-key, code-based, and multivariate cryptography. In this seminar, the speaker will first recall the core idea behind MPC-in-the-Head. They then will discuss how the paradigm has evolved into the recent VOLE-in-the-Head and TC-in-the-Head frameworks through the lens of Polynomial IOPs. Introduced in 2023, these frameworks underpin today’s MPCitH-based NIST candidates and enable signature sizes in the 2.5–5 kB range. The seminar will conclude by positioning MPCitH schemes within the broader landscape of post-quantum signatures, and by highlighting current efforts to port MPCitH-based implementations to embedded platforms.
