Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rn
as the foundation for secure cryptographic systems. Attractive features of lattice cryptography …

The learning with errors (LWE) problem has become a central building block of modern
cryptographic constructions. This work collects and presents hardness results for concrete …

Indistinguishability obfuscation, introduced by [Barak et. al. Crypto 2001], aims to compile
programs into unintelligible ones while preserving functionality. It is a fascinating and …

A key tool for building differentially private systems is adding Gaussian noise to the output of
a function evaluated on a sensitive dataset. Unfortunately, using a continuous distribution …

Abstract The National Institute of Standards and Technology is in the process of selecting
publickey cryptographic algorithms through a public, competition-like process. The new …

Smart-card based password authentication has been the most widely used two-factor
authentication (2FA) mechanism for security-critical applications (eg, e-Health, smart grid …

Along with applying blockchain technology in the health care service system (HSS), many
distributed solutions have been proposed to solve the centralized, data island problems …

This document is the supporting documentation of Falcon. It is organized as follows. Chapter
2 explains the overall design of Falcon and its rationale. Chapter 3 is a complete …

At IEEE Security & Privacy 2015, Bos, Costello, Naehrig, and Stebila proposed an
instantiation of Peikert's ring-learning-with-errors–based (Ring-LWE) key exchange protocol …

Many recent private set intersection (PSI) protocols encode input sets as polynomials. We
consider the more general notion of an oblivious key-value store (OKVS), which is a data …
