A STRUCTURED AGGREGATE SIGNATURE SCHEME WITH PAIRING-BASED CRYPTOGRAPHY
Masaki Inamura, Keiichi Iwamura · 2013
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 sig-nature 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 sign-ers, another scheme that is based on an aggregate signature scheme is required. To resolve the above problem, a de-noted 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.
