异步分布式密钥生成技术综述
Survey of Asynchronous Distributed Key Generation Techniques
摘要
Abstract
Distributed key generation technology has garnered significant attention in recent years.It enables participating parties to collaboratively generate public-private key pairs without relying on a trusted third party,utilizing threshold secret sharing.This makes it a fundamental building block for decentralized technologies like threshold signatures and blockchain.Traditional distributed key generation protocols typically assume a synchronous network,making them vulnerable to attacks in practical asynchronous environments.To address this challenge,recent research has proposed asynchronous distributed key generation schemes,which can effectively initialize threshold cryptosystems without requiring a global clock.However,these schemes are heavily dependent on intricate underlying cryptographic knowledge,along with their associated setups and constraints,thereby rendering the overall system architecture complex and difficult to construct.This paper presents a modular analysis of the key components of asynchronous distributed key generation technology,starting from its architectural perspective.The definition and basic settings of asynchronous distributed key generation technology is clearly defined,and its system architecture is described,which is divided into a random generation module and a consensus generation module according to the execution process and functions.This paper classifies and gradually describes the asynchronous secret sharing technology relied upon by the randomness generation module and the asynchronous Byzantine consensus technology relied upon by the consensus generation module,and systematically introduces the relevant underlying cryptographic knowledge.This paper introduces the application scenarios of asynchronous distributed key generation technology,summarizes and looks forward to its current important challenges and future research directions.关键词
