Internet of Things (IoT) allows billions of physical objects to be connected to collect and
exchange data for offering various applications, such as environmental monitoring …

We construct new multi-signature schemes that provide new functionality. Our schemes are
designed to reduce the size of the Bitcoin blockchain, but are useful in many other settings …

We describe a new Schnorr-based multi-signature scheme (ie, a protocol which allows a
group of signers to produce a short, joint signature on a common message) called MuSig …

A multi-signature scheme enables a group of signers to produce a compact, joint signature
on a common document, and has many potential uses. However, existing schemes impose …

The secret keys of critical network authorities--such as time, name, certificate, and software
update services--represent high-value targets for hackers, criminals, and spy agencies …

Digital signature is a fundamental primitive with numerous applications. Following the
development of pairing-based cryptography, several taking advantage of this setting have …

Non-interactive batch arguments for NP provide a way to amortize the cost of NP verification
across multiple instances. They enable a prover to convince a verifier of multiple NP …

We propose and investigate the notion of aggregate message authentication codes (MACs)
which have the property that multiple MAC tags, computed by (possibly) different senders on …

A multi-signature scheme allows a group of signers to collaboratively sign a message,
creating a single signature that convinces a verifier that every individual signer approved the …

A proxy signature scheme permits an entity to delegate its signing rights to another. These
schemes have been suggested for use in numerous applications, particularly in distributed …
