Key-and-Argument-Updatable QA-NIZKs
BPK model CRS model QA-NIZK
font style='font-size:12px;'>
2019/4/3
There are several new efficient approaches to decrease the trust in the CRS creators in the case of non-interactive zero knowledge (NIZK) in the CRS model. Recently, Groth et al. (CRYPTO 2018) defined...
Augmented Black-Box Zero-Knowledge Simulation And Zero Knowledge Argument for NP
zero-knowledge proofs (arguments) black-box simulation constant- round
font style='font-size:12px;'>
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...
An Efficient Pairing-Based Shuffle Argument
Common reference string generic group model mix-net
font style='font-size:12px;'>
2017/9/18
We prove the knowledge-soundness of the first two subarguments in the generic bilinear group model, and the culpable soundness of the third subargument under a KerMDH assumption. This proves the sound...
A Shuffle Argument Secure in the Generic Model
Common reference string generic bilinear group model mix-net
font style='font-size:12px;'>
2016/12/9
We propose a new random oracle-less NIZK shuffle argument. It has a simple structure, where the first verification equation ascertains that the prover has committed to a permutation matrix, the second...
Spooky Interaction and its Discontents: Compilers for Succinct Two-Message Argument Systems
Arguments Interactive Proofs
font style='font-size:12px;'>
2016/3/18
We are interested in constructing short two-message arguments for various languages, where
the complexity of the verifier is small (e.g. linear in the input size, or even sublinear if it is
coded pr...
Zero-knowledge Argument for Polynomial Evaluation with Application to Blacklists
Zero-knowledge argument discrete logarithm polynomial evaluation
font style='font-size:12px;'>
2016/1/3
Verification of a polynomial’s evaluation in a secret committed value plays a role in cryptographic applications such as non-membership or membership proofs. We construct a novel special honest verifi...
Efficient Culpably Sound NIZK Shuffle Argument without Random Oracles
Bilinear pairings CRS model mix-net
font style='font-size:12px;'>
2015/12/21
One way to guarantee security against malicious voting servers is to use NIZK shuffle
arguments. Up to now, only two NIZK shuffle arguments in the CRS model have been proposed. Both
arguments are re...
A More Efficient Computationally Sound Non-Interactive Zero-Knowledge Shuffle Argument
cryptographic protocols / Bilinear pairings cryptographic shuffle non-interactive zero-knowledge progression-free sets
font style='font-size:12px;'>
2012/3/27
We propose a new pairing-based non-interactive perfectly zero-knowledge shuffle argument that has smaller communication and is based on more standard computational cryptographic assumptions than the o...
A constant-round resettably-sound resettable zero-knowledge argument in the BPK model
foundations / Resettable zero-knowlege Resettable sound
font style='font-size:12px;'>
2012/3/27
In resetting attacks against a proof system, a prover or a verifier is reset and enforced to use the same random tape on various inputs as many times as an adversary may want. Recent deployment of clo...
Fixed Argument Pairings
Pairings Miller’s algorithm Tate pairing ate pairing precomputation
font style='font-size:12px;'>
2010/7/14
A common scenario in many pairing-based cryptographic protocols is that one argument in the pairing is fixed as a long term secret key or a constant parameter in the system. In these situations,...
An argument for Hamiltonicity
Hamiltonicity Schwartz-Zippel lemma characteristic polynomial
font style='font-size:12px;'>
2009/6/8
A constant-round interactive argument is introduced to show exis-
tence of a Hamiltonian cycle in a directed graph. Graph is represented
with a characteristic polynomial, top coefficient of a verifi...

font style='font-size:12px;'>
2009/6/5
A protocol is introduced to show knowledge of a codeword of Goppa
code and Goppa polynomial. Protocol does not disclosure any useful
information about the codeword and polynomial coefficients. A rel...

2009/1/8
Using a model based on probabilistic functions (PF), it’s introduced the concept of
perfect zero knowledge (PZK) commitment scheme (CS) allowing quasigroupic homomorphic
commitment (QHC). Using QHC ...
