    • Generic constructions of master-key KDM secure attribute-based encryption 

      Pan, Jiaxin; Qian, Chen; Wagner, Benedikt (Peer reviewed; Journal article, 2023)
      Master-key key-dependent message (mKDM) security is a strong security notion for attribute-based encryption (ABE) schemes, which has been investigated in recent years. This line of research was started with identity-based ...

    • Signed (Group) Diffie–Hellman Key Exchange with Tight Security 

      Pan, Jiaxin; Qian, Chen; Ringerud, Magnus (Peer reviewed; Journal article, 2022)
      We propose the first tight security proof for the ordinary two-message signed Diffie–Hellman key exchange protocol in the random oracle model. Our proof is based on the strong computational Diffie–Hellman assumption and ...
