Multi-signatures are protocols that allow a group of signers to jointly produce a single
signature on the same message. In recent years, a number of practical multi-signature …

Threshold digital signatures enable a distributed execution of signature functionalities and
will play a crucial role in the security of emerging decentralized next-generation networked …

Blockchain systems, as append-only ledgers, are typically associated with linearly growing
participation costs. Therefore, for a blockchain client to interact with the system (query or …

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 …

Smart Parking Services (SPSs) enable cruising drivers to find the nearest parking lot with
available spots, reducing the traveling time, gas, and traffic congestion. However, drivers risk …

Schnorr signatures are a popular choice due to their simplicity, provable security, and linear
structure that enables relatively easy threshold signing protocols. The deterministic variant of …

The security of secret keys for blockchain-based applications is increasingly important, partly
because the theft of secret keys will render a significant financial loss. To guarantee the …

Abstract Transport Layer Security (TLS) establishes an authenticated and confidential
channel to deliver data for almost all Internet applications. A recent work (Zhang et al …

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 …

We present an EdDSA-compatible multi-party digital signature scheme that supports an
offline participant during the key-generation phase, without relying on a trusted third party …
