Bootstrapping Consensus Without Trusted Setup: Fully Asynchronous Distributed Key Generation
threshold cryptography distributed cryptography asynchronous consensus
2019/9/16
In this paper, we present the first fully asynchronous distributed key generation (ADKG) algorithm as well as the first distributed key generation algorithm that can create keys with a dual (f,2f+1)&#...
ETHDKG: Distributed Key Generation with Ethereum Smart Contracts
Distributed Key Generation DKG Ethereum
2019/8/30
Distributed key generation (DKG) is a fundamental building block for a variety of cryptographic schemes and protocols, such as threshold cryptography, multi-party coin tossing schemes, public randomne...
Fast Secure Multiparty ECDSA with Practical Distributed Key Generation and Applications to Cryptocurrency Custody
ECDSA threshold cryptography
2018/11/5
ECDSA is a standardized signing algorithm that is widely used in TLS, code signing, cryptocurrency and more. Due to its importance, the problem of securely computing ECDSA in a distributed manner (kno...
Large-scale storage systems often attempt to achieve two seemingly conflicting goals: (1) the systems need to reduce the copies of redundant data to save space, a process called deduplication; and (2)...
Practical Distributed Key Generation Scheme and Its application
Threshold cryptography bivariate polynomials distributed key generation
2009/9/11
Generating a distributed key, where a constant fraction of
the players can reconstruct the key, is an essential component of thresh-
old cryptography. Previous solutions are based on univariate poly...
An Adaptively Secure Distributed Key Generation Scheme Against General Adversary without Erasure
2007/11/2
AbstractTransformation of the widely used Pedersen's Verifiable Secret Sharing (Pedersen-VSS) to Pedersen-VSS-General secure against general adversary is first presented. Then a misunderstanding about...
