  2024-05-19 · 35 citations

  article

  We propose hinTS — a new threshold signature scheme built on top of the widely used BLS signatures. Our scheme enjoys the following attractive features:A silent setup process where the joint public key of the parties is computed as a deterministic function of their locally computed public keys.Support for dynamic choice of thresholds and signers, after the silent setup, without further interaction.Support for general access policies; in particular, native support for weighted thresholds with zer…
