Big data drive multidimensional convergence and profound innovations among industries
and provide novel ways of exploring the world. As they significantly create economic and …

In vehicular ad hoc networks (VANETs), the security and privacy of vehicle data are core
issues. In order to analyze vehicle data, they need to be computed. Encryption is a common …

We construct a two-message oblivious transfer (OT) protocol without setup that guarantees
statistical privacy for the sender even against malicious receivers. Receiver privacy is game …

We construct a four round secure multip arty computation (MPC) protocol in the plain model
that achieves security against any dishonest majority. The security of our protocol relies only …

We devise a new partitioned simulation technique for MPC where the simulator uses
different strategies for simulating the view of aborting adversaries and non-aborting …

Abstract Threshold Fully Homomorphic Encryption (ThFHE) enables arbitrary computation
over encrypted data while keeping the decryption key distributed across multiple parties at …

We present new constructions of round-efficient, or even round-optimal, Multi-Party
Computation (MPC) protocols from Oblivious Transfer (OT) protocols. Our constructions …

Secure multi-party computation (MPC) is a central cryptographic task that allows a set of
mutually distrustful parties to jointly compute some function of their private inputs where …

Non-malleable commitments are a fundamental cryptographic tool for preventing
(concurrent) man-in-the-middle attacks. Since their invention by Dolev, Dwork, and Naor in …

We present a new approach towards constructing round-optimal secure multiparty
computation (MPC) protocols against malicious adversaries without trusted setup …
