Underwater structures that can change their shapes dynamically, the way fish do, push through water much more efficiently than conventional rigid hulls. But constructing deformable devices that can ch...
Compact and Scalable Arbitrary-centered Discrete Gaussian Sampling over Integers
Lattice-based crypto discrete Gaussian sampling implementation
2019/9/16
The arbitrary-centered discrete Gaussian sampler is a fundamental subroutine in implementing lattice trapdoor sampling algorithms. However, existing approaches typically rely on either a fast implemen...
Information Conservational Security with “Black Hole” Keypad Compression and Scalable One-Time Pad — A Quantum Intelligence Approach to Pre- and Post-Quantum Cryptography
Pre- and Post-Quantum Cryptography Scalable One-Time Pad (S-OTP) Information Conservational Security (ICS)
2019/8/14
Whereas it is widely deemed impossible to overcome the optimality of the one-time pad (OTP) cipher in pre- and post-quantum cryptography, this work shows that the optimality of information theoretic s...
Scalable Private Set Union from Symmetric-Key Techniques
Private Set Union Private Membership Test
2019/7/4
We present a new efficient protocol for computing private set union (PSU). Here two semi-honest parties, each holding a dataset of known size (or of a known upper bound), wish to compute the union of ...
Robust and Scalable Consensus for Sharded Distributed Ledgers
Blockchain sharding randomness
2019/6/12
ByzCoin, a promising alternative of Bitcoin, is a scalable consensus protocol used as a building block of many research and enterprise-level decentralized systems. In this paper, we show that ByzCoin ...
Trustless, Censorship-Resilient and Scalable Votings in the Permission-based Blockchain Model
DAO voting functional encryption
2019/6/4
Voting systems are the tool of choice when it comes to settle an agreement of different opinions. We propose a solution for a trustless, censorship-resilient and scalable electronic voting platform. B...
Linearly-Homomorphic Signatures and Scalable Mix-Nets
Anonymity random shuffling linearly-homomorphic signatures
2019/5/23
Anonymity is a primary ingredient for our digital life. Several tools have been designed to address it such as, for authentication, blind signatures, group signatures or anonymous credentials and, for...
Efficient and Scalable Universal Circuits
Universal circuit private function evaluation function hiding
2019/4/3
A universal circuit (UC) can be programmed to simulate any circuit up to a given size n by specifying its program inputs. It provides elegant solutions in various application scenarios, e.g., for priv...
Financial exchanges are typically built out of two trusted components: a trade matching and a trade settlement system. With the advent of decentralized ledgers, that perform transactions without a tru...
Design and Implementation of a Fast and Scalable NTT-Based Polynomial Multiplier Architecture
Number Theoretic Transform Large-Degree Polynomial Multiplication Fan-Vercauteren
2019/2/27
In this paper, we present an optimized FPGA implementation of a novel, fast and highly parallelized NTT-based polynomial multiplier architecture, which proves to be effective as an accelerator for lat...
DEXON: A Highly Scalable, Decentralized DAG-Based Consensus Algorithm
Blockchain Blocklattice Consensus
2018/11/20
A blockchain system is a replicated state machine that must be fault tolerant. When designing a blockchain system, there is usually a trade-off between decentralization, scalability, and security. In ...
Scalable One-Time Pad --- From Information Theoretic Security to Information Conservational Security
Information Conservational Security Data Compression Quantum-Fuzzy Collective Precision
2018/11/16
Whereas it is widely deemed an impossible task to scale One-Time Pad (OTP) without sacrificing information theoretic security or network traffic, this paper presents a paradigm of Scalable OneTime Pad...

Blockchain Consensus protocol Byzantine agreement
2018/11/14
We present Helix, a Byzantine fault tolerant and scalable consensus algorithm for fair ordering of transactions among nodes in a distributed network. In Helix, one among the network nodes proposes a p...
Turning HATE Into LOVE: Homomorphic Ad Hoc Threshold Encryption for Scalable MPC
MPC threshold encryption obfuscation
2018/11/5
We explore large-scale fault-tolerant multiparty computation on a minimal communication graph. Our goal is to be able to privately aggregate data from thousands of users - for example, in order to obt...
