Dr. Anshu Yadav (IST Austria) discussed her Asiacrypt 2024-accepted work on strengthening lattice-based threshold cryptography. Her research addresses a gap in Boneh et al.’s 2018 framework by allowing adversaries to adaptively query partial signatures on target messages without compromising security, provided they lack the threshold to reconstruct a final signature.

This enhances the practicality of post-quantum-secure threshold systems like signatures and encryption. The work redefines security for universal thresholdizers, enabling safer decentralised protocols. Dr. Yadav holds a PhD from IIT Madras under Prof. Shweta Agrawal.
