Brief announcement: improving social-network-based sybil-resilient node admission control
We present Gatekeeper, a decentralized protocol that performs Sybil-resilient node admission control based on a social network. Gatekeeper can admit most honest nodes while limiti...

Partial information spreading with application to distributed maximum coverage
This paper addresses partial information spreading among n nodes of a network. As opposed to traditional information spreading, where each node has a message that must be received...

Verifying linearizability with hindsight
We present a proof of safety and linearizability of a highlyconcurrent optimistic set algorithm. The key step in our proof is the Hindsight Lemma, which allows a thread to infer t...

Hybrid-secure MPC: trading information-theoretic robustness for computational privacy
Most protocols for distributed, fault-tolerant computation, or multi-party computation (MPC), provide security guarantees in an all-or-nothing fashion: If the number of corrupted p...

Constant RMR solutions to reader writer synchronization
We study Reader-Writer Exclusion [1], a well-known variant of the Mutual Exclusion problem [2] where processes are divided into two classes–readers and writers–and multiple re...
