ePrint Report: Scalable and Adaptively Secure Any-Trust Distributed Key Generation and All-hands Checkpointing

Hanwen Feng, Tiancheng Mai, Qiang Tang

The classical distributed key generation protocols (DKG) are resurging due to their widespread applications in blockchain. While efforts have been made to improve DKG communication, practical large scale deployments are still yet to come, due to various challenges including broadcast channel scalability and worst-case complaint phase.
In this paper, we propose a practical DKG for DL-based cryptosystems, with only (quasi-)linear computation/communication …
