We propose hinTS—a new threshold signature scheme built on top of the widely used BLS
signatures. Our scheme enjoys the following attractive features: A silent setup process …

WPA3-Personal renders the Simultaneous Authentication of Equals (SAE) password-
authenticated key agreement method mandatory. The scheme achieves forward secrecy …

Elliptic curves have become key ingredients for instantiating zero-knowledge proofs and
more generally proof systems. Recently, there have been many tailored constructions of …

Attribute-based encryption (ABE) enables fine-grained access control on encrypted data and
has a large number of practical applications. This paper presents FABEO: faster pairing …

We introduce a new notion of multiverse threshold signatures (MTS). In an MTS scheme,
multiple universes–each defined by a set of (possibly overlapping) signers, their weights …

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 …

We generalize the Bernstein-Yang (BY) algorithm [11] for constant-time modular inversion to
compute the Kronecker symbol, of which the Jacobi and Legendre symbols are special …

Pake allows two parties who share a memorable password to securely establish a strong
secret key. It has been deployed in many applications around us, such as iCloud service, Wi …

Hashing arbitrary values to points on an elliptic curve is a required step in many
cryptographic constructions, and a number of techniques have been proposed to do so over …

Outsourced decryption attribute-based encryption (OD-ABE) is emerging as a promising
cryptographic tool to provide efficient fine-grained access control for data accessing and …
