Distributed Key Generation for the Internet [PDF]

2009 29th IEEE International Conference on Distributed Computing Systems, 2009
Although distributed key generation (DKG) has been studied for some time, it has never been examined outside of the synchronous setting. We present the first realistic DKG architecture for use over the Internet. We propose a practical system model and define an efficient verifiable secret sharing scheme in it.

Aggregatable Distributed Key Generation [PDF]

, 2021
In this paper, we introduce a distributed key generation (DKG) protocol with aggregatable and publicly-verifiable transcripts. Compared with prior publicly-verifiable approaches, our DKG reduces the size of the final transcript and the time to verify it from \(\mathcal {O}(n^2)\) to \(\mathcal {O}(n \log {n})\), where n denotes the number of parties ...

Optimization of end-wall fence in turbine based on response surface methodology and genetic algorithm

Case Studies in Thermal Engineering, 2023
Secondary flow loss accounts for a large proportion of the internal flow loss in turbine stages. The use of end-wall fences can effectively reduce secondary flow loss. In this study, the White cascade was taken as the research object, and the position of

Federated distributed key generation

Future Generation Computer Systems
Distributed Key Generation (DKG) underpins threshold cryptography in many systems, including decentralized wallets, validator key ceremonies, cross-chain bridges, threshold signatures, secure multiparty computation, and internet voting. Classical ($t$,$n$)-DKG assumes a fixed group of n parties and a global threshold $t$, requiring full and timely ...
