      Wang, Yuyu; Pan, Jiaxin; Chen, Yu (Peer reviewed; Journal article, 2021)
    • 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 ...

    • 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 ...
