We present a three-round protocol for threshold ECDSA signing with malicious security
against a dishonest majority, which information-theoretically UC-realizes a standard …

Metaverse brings unlimited space and tremendous potential since it is an integrated
application of multiple fundamental technologies such as artificial intelligence, blockchain …

Abstract Structure-preserving signatures (SPS) have emerged as an important cryptographic
building block, as their compatibility with the Groth-Sahai (GS) NIZK framework allows to …

Asynchronous distributed key generation (ADKG) is a strong-robustness key management
technology to bootstrap threshold cryptosystems without a global clock, which can enable …

Threshold signatures as a method to realize multi-party cooperation and trust distribution in
blockchain have been widely studied in recent years. However, among these researches …

Edwards-curve digital signature algorithm (EdDSA) is a highly efficient scheme with a short
key size. It is derived from the threshold-friendly Schnorr signatures and is covered by the …

Digital signatures underpin identity, authenticity, and trust in modern computer systems.
Cryptography research has shown that it is possible to prove possession of a valid message …

With the demand of cryptocurrencies, threshold ECDSA recently regained popularity. So far,
several methods have been proposed to construct threshold ECDSA, including the usage of …

Abstract Proof-of-Authorization (PoA) consensus algorithms are widely used in
permissioned blockchain networks due to their high throughput, security, and efficiency …
