Design of a provably secure identity-based digital multi-signature scheme using biometrics and fuzzy extractor

Abstract

A novel biometric identity-based digital multi-signature (BIO-IDMS) scheme is put forwarded in this paper. The proposed scheme is constructed with the help of fuzzy extractor and elliptic curve bilinear pairings. Furthermore, we designed the formal model and the security model of the proposed BIO-IDMS scheme. The formal security analysis demonstrates that the forgery of the proposed scheme is infeasible in the random oracle model based on the intractability assumption of the computational Diffie–Hellman (CDH) problem. The proposed scheme outperforms in terms of computational cost compared with other related existing multi-signature schemes. Copyright © 2016 John Wiley & Sons, Ltd.
