Zero-knowledge efficiency privacy-preserving protocols
2019/8/30
We present a new 4-move special honest-verifier zero-knowledge proof of knowledge system for proving that a vector of Pedersen commitments opens to a so-called "one-hot" vector (i.e., to a vector from...
Non-Interactive Zero Knowledge Proofs in the Random Oracle Model
FS transform NIZK random oracle model
2019/8/22
The Fiat-Shamir (FS) transform is a well known and widely used technique to convert any constant-round public-coin honest-verifier zero-knowledge (HVZK) proof or argument system CIPC=(Prov,Ver)CIPC=(P...
Improvements in Everlasting Privacy: Efficient and Secure Zero Knowledge Proofs
Voting Everlasting Privacy Zero Knowledge Proofs
2019/8/8
Verifiable electronic voting promises to ensure the correctness of elections even in the presence of a corrupt authority, while providing strong privacy guarantees. However, few practical systems with...
Efficient Perfectly Sound One-message Zero-Knowledge Proofs via Oracle-aided Simulation
zero-knowledge NIZK RSA ZAP
2019/6/26
In this paper we put forth new one-message proof systems for several practical applications, like proving that an El Gamal ciphertext (over a multiplicative group) decrypts to a given value and correc...
Timed Signatures and Zero-Knowledge Proofs -Timestamping in the Blockchain Era-
Blockchain Digital Signatures Zero-knowledge Proofs
2019/6/5
Timestamping is an important cryptographic primitive with numerous applications. The availability of a decentralized blockchain such as that offered by the Bitcoin protocol offers new possibilities to...

2019/5/9
We devise new techniques for design and analysis of efficient lattice-based zero-knowledge proofs (ZKP). First, we introduce one-shot proof techniques for non-linear polynomial relations of degree k≥2...
Libra: Succinct Zero-Knowledge Proofs with Optimal Prover Computation
Zero knowledge proof interactive proof polynomial delegation
2019/4/1
We present Libra, the first zero-knowledge proof system that has both optimal prover time and succinct proof size/verification time. In particular, if C is the size of the circuit being proved (i) the...
How to Prove a Secret: Zero-Knowledge Proofs on Distributed Data via Fully Linear PCPs
linear PCPs proof systems zero knowledge
2019/3/1
We introduce and study the notion of fully linear probabilistically checkable proof systems. In such a proof system, the verifier can make a small number of linear queries that apply jointly to the in...
LegoSNARK: Modular Design and Composition of Succinct Zero-Knowledge Proofs
zero knowledge implementation zk-SNARKs framework
2019/2/26
We study the problem of building SNARKs modularly by linking small specialized “proof gadgets" SNARKs in a lightweight manner. Our motivation is both theoretical and practical. On the theoretical side...
