Scalable and Secure Computation Among Strangers: Message-Competitive Byzantine Protocols

2019 · arXiv (Cornell University)

Motivated, in part, by the rise of permissionless systems such as Bitcoin where arbitrary nodes (whose identities are not known apriori) can join and leave at will, we extend established research in scalable Byzantine agreement …

Bootstrapping Public Blockchains Without a Trusted Setup

2019

We propose a protocol that allows the participants of a permissionless decentralized system to agree on a set of identities in the presence of a computationally-bounded Byzantine adversary. Our protocol guarantees that the fraction of …

TorBricks: Blocking-Resistant Tor Bridge Distribution

2016 · ArXiv.org

Tor is currently the most popular network for anonymous Internet access. It critically relies on volunteer nodes called bridges for relaying Internet traffic when a user's ISP blocks connections to Tor. Unfortunately, current methods for …
