Robust Threshold ECDSA with Online-Friendly Design in Three Rounds
Guofeng Tang, Haiyang Xue
IEEE Symposium on Security and Privacy 2025 · Day 1 · Threshold and Post-Quantum Cryptography
This talk, presented by Guofeng Tang and Haiyang Xue from Simple Management University, introduces a groundbreaking advancement in **threshold ECDSA (Elliptic Curve Digital Signature Algorithm)**. The work focuses on developing a scheme that is both **robust** and **online-friendly**, while achieving a minimal communication overhead of just three rounds. This combination of properties addresses significant challenges in deploying secure and efficient distributed signature systems, particularly for high-value applications like cryptocurrency.
