In this paper, we introduce the problem of Asynchronous Data Dissemination (ADD).
Intuitively, an ADD protocol disseminates a message to all honest nodes in an …

In this paper, we present the first Asynchronous Distributed Key Generation (ADKG)
algorithm which is also the first distributed key generation algorithm that can generate …

Secure multi-party computation (MPC) allows a set of n parties to jointly compute a function
over their private inputs. The seminal works of Ben-Or, Canetti and Goldreich [STOC'93] and …

Despite significant recent progress toward making multi-party computation (MPC) practical,
no existing MPC library offers complete robustness---meaning guaranteed output delivery …

Regular access to unpredictable and bias-resistant randomness is important for applications
such as blockchains, voting, and secure distributed computing. Distributed random beacon …

We describe robust high-throughput threshold protocols for generating Schnorr signatures in
an asynchronous setting with potentially hundreds of parties. The protocols run a single …

Distributed key generation (DKG) protocols are an essential building block for threshold
cryptosystems. Many DKG protocols tolerate up to ts< n/2 corruptions assuming a well …

We present and analyze a new protocol that provides a distributed ECDSA signing service,
with the following properties:* it works in an asynchronous communication model;* it works …

Secure multiparty computation (MPC) allows a set of n parties to jointly compute a function
on their private inputs. In this work, we focus on the information-theoretic MPC in the …
