Improved YOSO Randomness Generation with Worst-Case Corruptions
Abstract
We study the problem of generating public unbiased randomness in a distributed manner within the recent You Only Speak Once (YOSO) framework for stateless multiparty computation, introduced by Gentry et al. in CRYPTO 2021. Such protocols are resilient to adaptive denial-of-service attacks and are, by their stateless nature, especially attractive in permissionless environments. While most works in the YOSO setting focus on independent random corruptions, we consider YOSO protocols with worst-case corruptions, a model introduced by Nielsen et al. in CRYPTO 2022.
Prior work on YOSO public randomness generation with worst-case corruptions designed information-theoretic protocols for
