Efficient Tightly-Secure Structure-Preserving Signatures and Unbounded Simulation-Sound QA-NIZK Proofs
Structure-preserving signatures QA-NIZK simulation-soundness
2019/9/16
We show how to construct structure-preserving signatures (SPS) and unbounded quasi-adaptive non-interactive zero-knowledge (USS QA-NIZK) proofs with a tight security reduction to simple assumptions, b...
Despite recent advances in the area of pairing-friendly Non-Interactive Zero-Knowledge proofs, there have not been many efficiency improvements in constructing arguments of satisfiability of quadratic...

2018/11/15
We construct the first (almost) tightly-secure unbounded-simulation-sound quasi-adaptive non-interactive zero-knowledge arguments (USS-QA-NIZK) for linear-subspace languages with compact (number of gr...

2018/11/13
While the CRS model is widely accepted for construction of non-interactive zero knowledge (NIZK) proofs, from the practical viewpoint, a very important question is to minimize the trust needed from th...

We show how to build a UC-Secure Oblivious Transfer in the presence of Adaptive Corruptions from Quasi-Adaptive Non-Interactive Zero-Knowledge proofs. Our result is based on the work of Jutla and Roy ...
Compactly Hiding Linear Spans: Tightly Secure Constant-Size Simulation-Sound QA-NIZK Proofs and Applications

2016/1/3
Quasi-adaptive non-interactive zero-knowledge (QA-NIZK) proofs is a powerful paradigm, suggested recently by Jutla and Roy (Asiacrypt'13), which is motivated by the Groth-Sahai seminal techniques for ...

SIMON and SPECK family ciphers have attracted the attention of cryptographers all over the world since proposed by NSA in June, 2013. At CHES 2015, Simeck, a new block cipher inspired from both SIMON ...
