On the Existence of Three Round Zero-Knowledge Proofs
zero-knowledge round complexity lower bound
2018/3/6
In this work, we study the feasibility of ZK proofs using non-black-box simulation. Our main result is that three round private-coin ZK proofs for NP do not exist (even w.r.t. non-black-box simulation...
Zero-Knowledge Proof of Decryption for FHE Ciphertexts
zero knowledge fully homomorphic encryption verifiable decryption
2018/1/11
Zero-knowledge proofs of knowledge and fully-homomorphic encryption are two areas that have seen considerable advances in recent years, and these two techniques are used in conjunction in the context ...
Efficient Adaptively Secure Zero-knowledge from Garbled Circuits
Zero-knowledge Garbled Circuits Adaptive Security
2018/1/11
Zero-knowledge (ZK) protocols are undoubtedly among the central primitives in cryptography, lending their power to numerous applications such as secure computation, voting, auctions, and anonymous cre...
Efficient Batch Zero-Knowledge Arguments for Low Degree Polynomials
Sigma-protocol zero-knowledge argument batch-verification
2018/1/11
The work of Bootle et al. (EUROCRYPT 2016) constructs an extremely efficient zero-knowledge argument for arithmetic circuit satisfiability in the discrete logarithm setting. However, the argument does...
Augmented Black-Box Zero-Knowledge Simulation And Zero Knowledge Argument for NP
zero-knowledge proofs (arguments) black-box simulation constant- round
2017/12/25
Zero knowledge property, proved by means of augmented black-box simulation, is called augmented black-box zero-knowledge. We present a 5-round statistical augmented black-box zero-knowledge argument f...
Post-Quantum Zero-Knowledge Proofs for Accumulators with Applications to Ring Signatures from Symmetric-Key Primitives
privacy-preserving cryptography provable security accumulator
2017/11/29
In this paper we address the construction of privacy-friendly cryptographic primitives for the post-quantum era and in particular accumulators with zero-knowledge membership proofs and ring signatures...
A Zero-Knowledge Version of vSQL
zero-knowledge arguments verifiable polynomial delegation
2017/11/28
Zero-knowledge arguments of knowledge are powerful cryptographic primitives that allow a computationally strong prover to convince a weaker verifier for the validity of an NP statement, without reveal...
Relaxed Lattice-Based Signatures with Short Zero-Knowledge Proofs
Lattices sigma protocols anonymous attribute tokens
2017/11/27
Higher-level cryptographic privacy-enhancing protocols such as anonymous credentials, voting schemes, and e-cash are often constructed by suitably combining signature, commitment, and encryption schem...
Promise Zero Knowledge and its Applications to Round Optimal MPC
Zero knowledge MPC Coin Tossing
2017/11/13
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 adversaries. The protagonist of ...
Proposal for Protocol on a Quorum Blockchain with Zero Knowledge
implementation zero knowledge
2017/11/13
In this paper, we present an implementation scheme of an RTGS on Quorum using the Solidity language. It is heavily inspired by the Schnorr signature protocol to verify the identity of the participants...
Efficient Designated-Verifier Non-Interactive Zero-Knowledge Proofs of Knowledge
Zero-knowledge proofs, Non-interactive proofs
2017/10/30
We propose a framework for constructing efficient designated-verifier non-interactive zero-knowledge proofs (DVNIZK) for a wide class of algebraic languages over abelian groups, under standard assumpt...
Compact Zero-Knowledge Proofs of Small Hamming Weight
zero-knowledge oblivious transfer ring signatures
2017/10/30
We introduce a new technique that allows to give a zero-knowledge proof that a committed vector has Hamming weight bounded by a given constant. The proof has unconditional soundness and is very compac...
Delayed-Input Non-Malleable Zero Knowledge and Multi-Party Coin Tossing in Four Rounds
delayed-input protocols non-malleable zero knowledge multi-party coin tossing
2017/9/26
4-round non-malleable zero knowledge (NMZK): Goyal et al. in FOCS 2014 showed the first 4-round one-one NMZK argument from one-way functions (OWFs). Their construction requires the prover to know the ...

zero knowledge resettable ZK resettable soundness
2017/9/25
In FOCS 2001 Barak et al. conjectured the existence of zero-knowledge arguments that remain secure against resetting provers and resetting verifiers. The conjecture was proven true by Deng et al. in F...
