In this whitepaper, we articulate a vision for the evolution of Chainlink beyond its initial
conception in the original Chainlink whitepaper. We foresee an increasingly expansive role …

We propose a novel paradigm for defining security of cryptographic protocols, called
universally composable security. The salient property of universally composable definitions …

Although they have been studied for a long time, distributed signature protocols have
garnered renewed interest in recent years in view of novel applications to topics like …

Recently some efforts were made towards capturing the security requirements from digital
signature schemes as an ideal functionality within a composable security framework. This …

Threshold signatures are one of the most important cryptographic primitives in distributed
systems. A popular choice of threshold signature scheme is the BLS threshold signature …

We construct the first actively-secure threshold version of the cryptosystem based on class
groups from the so-called CL framework (Castagnos and Laguillaumie, 2015). We show …

The resurging interest in Byzantine fault tolerant systems will demand more scalable
threshold cryptosystems. Unfortunately, current systems scale poorly, requiring time …

A threshold signature scheme distributes the ability to generate signatures through
distributed key generation and signing protocols. A threshold signature scheme should be …

This paper presents a novel framework for generic construction of hybrid encryption
schemes secure against chosen ciphertext attack. Our new framework yields new and more …

Threshold cryptography is a fundamental distributed computational paradigm for enhancing
the availability and the security of cryptographic public-key schemes. It does it by dividing …
