Explore a comprehensive conference talk on Asynchronous Distributed Key Generation (ADKG) presented at IEEE. Delve into the intricacies of ADKG[n,t,E] system models, applications, and threshold secret sharing. Examine existing works and new results in the field, including evaluation metrics such as average runtime, bandwidth usage, and computation costs. Learn about the general DKG framework, challenges in asynchrony, and the three main phases: sharing, key proposal, and key derivation. Gain insights into Asynchronous Complete Secret Sharing (ACSS) for random secrets and its performance implications. Enhance your understanding of distributed cryptography and its practical applications in secure, decentralized systems.
