Abstract
Methods and systems are provided for generating and verifying signatures of digital messages communicated between signers and verifiers. Using bilinear mappings, such as Weil or Tate pairings, these methods and systems enable generation and verification of efficient multisignatures, identity-based ring signatures, hierarchical proxy signatures, and hierarchical online/offline signatures.
