Weak Zero-Knowledge via the Goldreich-Levin Theorem
Obtaining three round zero-knowledge from standard cryptographic assumptions has remained a challenging open problem. Meanwhile, there has been...

Efficient Non-interactive Zero-Knowledge Proof for Graph 3-Coloring Problem
Zero-knowledge proof (ZKP) has a crucial role in the construction of cryptographic protocols and privacy protection. One of the core research...

On Publicly-Accountable Zero-Knowledge and Small Shuffle Arguments
Constructing interactive zero-knowledge arguments from simple assumptions with small communication complexity and good computational efficiency is an...

Steganography-Free Zero-Knowledge
We revisit the well-studied problem of preventing steganographic communication in multi-party communications. While this is known to be a provably...

Zero-Knowledge Proofs for SIDH Variants with Masked Degree or Torsion
The polynomial attacks on SIDH by Castryck, Decru, Maino, Martindale and Robert have shown that, while the general isogeny problem is still...
-
Lattice-based zero-knowledge arguments for additive and multiplicative relations
In this work, we propose new lattice-based protocols which are used to prove additive and multiplicative relations of committed integers. We...

Oblivious Transfer from Zero-Knowledge Proofs
We provide a generic construction to turn any classical Zero-Knowledge (ZK) protocol into a composable (quantum) oblivious transfer (OT) protocol,...
