Non-Interactive Zero-Knowledge Proofs with Fine-Grained Security
Wang, Yuyu; Pan, Jiaxin (Peer reviewed; Journal article, 2022)We construct the first non-interactive zero-knowledge (NIZK) proof systems in the fine-grained setting where adversaries’ resources are bounded and honest users have no more resources than an adversary. More concretely, ... -
Shorter QA-NIZK and SPS with Tighter Security
Abe, Masayuki; Jutla, Charanjit; Ohkubo, Miyako; Pan, Jiaxin; Roy, Arnab; Wang, Yuyu (Chapter, 2019)Quasi-adaptive non-interactive zero-knowledge proof (QA-NIZK) systems and structure-preserving signature (SPS) schemes are two powerful tools for constructing practical pairing-based cryptographic schemes. Their efficiency ... -
A Simple and Efficient Framework of Proof Systems for NP
Wang, Yuyu; Su, Chuanjie; Pan, Jiaxin; Chen, Yu (Peer reviewed; Journal article, 2023) -
Unconditionally Secure NIZK in the Fine-Grained Setting
Wang, Yuyu; Pan, Jiaxin (Peer reviewed; Journal article, 2022)Non-interactive zero-knowledge (NIZK) proof systems are often constructed based on cryptographic assumptions. In this paper, we propose the first unconditionally secure NIZK system in the AC0 -fine-grained setting. More ...
