    • Compact Structure-Preserving Signatures with Almost Tight Security 

      Abe, Masayuki; Hofheinz, Dennis; Nishimaki, Ryo; Ohkubo, Miyako; Pan, Jiaxin (Peer reviewed; Journal article, 2023)
      In structure-preserving cryptography, every building block shares the same bilinear groups. These groups must be generated for a specific, a priori fixed security level, and thus, it is vital that the security reduction ...

    • 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 ...
