Functional Commitments for All Functions, with Transparent Setup and from SIS
A functional commitment scheme enables a user to concisely commit to a function from a specified family, then later concisely and verifiably reveal...

A discrete SIS-model built on the strictly positive scheme
In this paper we introduce and analyze a discrete SIS epidemic model for a homogeneous population. As a discretization method the strictly positive...

LaBRADOR: Compact Proofs for R1CS from Module-SIS
The most compact quantum-safe proof systems for large circuits are PCP-type systems such as Ligero, Aurora, and Shockwave, that only use weak...

Lattice-Based Functional Commitments: Fast Verification and Cryptanalysis
A functional commitment allows a user to commit to an input $$\textbf{x}\in...

On the (M)iNTRU Assumption in the Integer Case
In AsiaCrypt 2019, Genise, Gentry, Halevi, Li and Micciancio put forth two novel and intriguing computational hardness hypotheses: The inhomogeneous...

SLAP: Succinct Lattice-Based Polynomial Commitments from Standard Assumptions
Recent works on lattice-based extractable polynomial commitments can be grouped into two classes: (i) non-interactive constructions that stem from...

Lattice-Based Key-Value Commitment Scheme with Key-Binding and Key-Hiding Properties
Blockchain plays an important role in distributed file systems, such as cryptocurrency. One of the important building blocks of blockchain is the...

Tagged Chameleon Hash from Lattices and Application to Redactable Blockchain
Chameleon hash (CH) is a trapdoor hash function. Generally it is hard to find collisions, but with the help of a trapdoor, finding collisions becomes...

Message-Restriction-Free Commitment Scheme Based on Lattice Assumption
A commitment scheme is a fundamental protocol and an essential component of basic cryptographic tasks, such as zero-knowledge identification. In...

Succinct Vector, Polynomial, and Functional Commitments from Lattices
Vector commitment schemes allow a user to commit to a vector of values...
-
Updatable, Aggregatable, Succinct Mercurial Vector Commitment from Lattice
Vector commitments (VC) and their variants attract a lot of attention due to their wide range of usage in applications such as blockchain and...

Shorter and Faster Identity-Based Signatures with Tight Security in the (Q)ROM from Lattices
We provide identity-based signature (IBS) schemes with tight security against adaptive adversaries, in the (classical or quantum) random oracle model...

On the usage of epidemiological models for information diffusion over twitter
The way information spreads through online social networks is popularly considered to be similar to how viruses spread through a population. In this...

Sigma Protocols for MQ, PKP and SIS, and Fishy Signature Schemes
This work presents sigma protocols to prove knowledge of:...

Short Identity-Based Signatures with Tight Security from Lattices
We construct a short and adaptively secure identity-based signature scheme tightly based on the well-known Short Integer Solution (SIS) assumption....

CTA: Confidential Transactions Protocol with State Accumulator
Considering the increasingly large storage of post-quantum RingCT-like protocols, we construct a blockchain-based confidential transactions protocol...

A Hierarchical Watermarking Scheme for PRFs from Standard Lattice Assumptions
A software watermarking scheme is to embed a “mark” or a message into a program in a cryptographic way. It is useful in proving ownership (e.g., in...

Puncturable Signature: A Generic Construction and Instantiations
Puncturable signature (PS), proposed by Bellare, Stepanovs and Waters at EUROCRYPT 2016, is a special kind of digital signature that supports a...
