Abstract:


In this study, we propose a new aggregate signature scheme with pairing-based cryptography that can describe the mixed/parallel structure of signers. Existing structured signature schemes are based on multisignature schemes, which are adapted for verification of a mixed/parallel structure if all signers sign the same document. However, if each signer wants to sign a document different from those of other signers, another scheme that is based on an aggregate signature scheme is required. To resolve the above problem, a denoted connective signature is generated in our scheme. In addition, our scheme is shown to be secure under the Gap-Diffie-Hellman assumption. Furthermore, we explain that our scheme is simple to construct, and its performance is efficient.
